Crystal Glass Nail File, 5.5 Inches, Free Carrying Case from Sassella

Ordinary nail files create tiny fractures in your nail which can weaken the nail and cause the nail to split and become brittle. Because the glass file is so hard and the filing surface so extremely fine, you can file in any direction without damaging the nail. It will leave your nails incredibly smooth! Amazingly the glass file works very well on extremely hard nails as well as very soft nails. Since the surface of the glass nail file is so fine and uniform, regular use will actually help grow more beautiful nails, they will be healthier and smoother.

Key features

  • Elegant glass file made from crystal in Czech Republic
  • A permanent file that never wears out
  • Prevents chipping and layering caused by traditional files
  • Filing can be done in any direction
  • Easy to clean and disinfect

Honest reviews


works ok

This works okay, but I found that it got dull pretty quickly. I read reviews before I purchased it but I think for the price i paid it isnt as good as it could be. I would have been better off just getting a few cheapies from the dollar store.

First Crystal File

Oh boo! At first I wrote a glowing review but it’s been 2 weeks and my file is.. glass! Ahahaha. I don’t know what’s wrong with it, but this damned thing has lost it’s grit.I guess I used it quite industrially, but damn!I’ll be ordering the opi next time.

Glass nall files are wonderful but

I wish I had gotten a longer file. It works, and is probably a very handy size for carrying about in a purse. At home though I would prefer one that is longer. It also is not as good as my mothers which has a finer bite.

Good quality, pricey

I really like the quality of these files (I even bought another one as a gift). Files the nails down precisely and quickly, and I feel it is less abrasive than traditional emery boards. I sometimes can gently file the surface of the nail, if needed. Easy to wash, and I always store it in the handy case, too. I think the product is a little pricey compared to the competition, and I’m not entirely sure it’s worth the full $10 (with shipping).

its alright

it comes with a case and i like the colors. it takes a while to actually file my nails down to the size i want with this one. when i use a normal file i get down to it quicker. i guess this is better for your nails so i try to use it more than the others.

Great nail file

I agree with all the other reviewers on Amazon. The nail file leaves a really smooth edge and I’m astonished that I lived this long without having one of these files. It cleans really easily, although I prefer to rinse it off every other use, since it does get sort of clogged up with nail dust.The only drawback of this file is that the feeling of drawing it across the edge of my nails sets my teeth slightly on edge. Does it affect anyone else? I end up not drawing it back and forth, but file in one direction only to minimize the vibrations. I cannot really describe what a weird feeling it is to use this file, but I enjoy the results too much to switch back.

Great discovery

I had never heard of class nail files before, and I thought they might be a gimmick, but it wasn’t a lot of money, so thought I would give it a try. It really is pretty good, and I do feel that the nails are much much smoother than regular files, so I would imagine that in the long-term they would lead to a lot less damage to the nails.

Beautiful, great working file.

I’ve been using my Miss Manicure nail file for over 6 years, the long metal one, and finally it’s come to its end. After no luck with finding another Miss Manicure, I went about looking at these new glass files. Some had poor reviews, but I found this one with great reviews and decided to give it a try, and I have not been disappointed.It files pretty well. It doesn’t leave that little residue strip of nail that’s still attached after filing, it just shaves it off clean (along with some dust that’s unavoidable of course). I’ve noticed my nails are much sharper. Someone mentioned in the other comments that they’ve noticed an improved nail growth since using this glass file, and I’ll say I have too. My nails are typically very thin and brittle, and break often. Though since using this, it’s decreased significantly. One or two broke in very different periods of time, due to me being careless.My only very small complaint, that I’ve read happens to some but not everyone, is that when filing back and forth, one way it will make this nasty grinding feeling on my nail, like nails on a chalkboard! Though it is easily fixed with just going in one direction (I’ve read this usually happens if your nails aren’t thick enough to stand the file going back and forth, so I didn’t take much off in the rating for this).The other is that it doesn’t seem to give me the smoothness I was able to achieve with my other file; as in after inspecting them, I find a spot or two that just won’t curve and smooth out, so I use my other file to even out the corner. I’m pretty picky with my nails though so I doubt it’ll be of much concern to many or anyone.4/5, one star taken for the two reasons combined. Great file and I love it 🙂

Good file. Does not rip nails but files smoothly. Nice case and well designed. Would recommend. It should last a very long time.

Cynthia New Knoxville, OH


Love this nail file! Best I’ve ever owned. I was skeptical to try a glass one, but boy am I glad I did!

Kristy Maysel, WV

This is the best nail file I have ever used!

This is the best nail file for natural nails, period. No snagging or peeling, in fact, your nail edges are as smooth as glass!

Winifred Coloma, CA

Purse Ready

Great tool to carry in purse. Nice carry case. Works well on nail does not damage. I like it very much.

Carolyn Livermore, CA

Great Nail File!

I love this glass nail file! I bought this after finding out crystal files are more gentle on nails; My nails have been growing so fast lately and I’ve always had problems with them peeling. I think this is a great buy and very nice quality file – I even got a free mini glass file included in the order which is a great bonus! I love that I will have this forever and not have to go back to using emery boards.

Jeanne Wolf Run, OH

Glass file

I had never heard of a glass nail file before finding this on Amazon. I like the feel of the file since it is not completely flat, but slightly curved. My nails are prone to flaking and breaking, especially in cold weather. This file has improved nail growth by preserving the nails as they are maintained. It takes your nails down effectively with minimal friction. Be careful not to remove more nail than you intend until you get used to this file.

Imogene Spring Valley, OH

Excellent file!

Love this file – I don’t have to worry about breaking it with the carrying case, and just keep it in my bag at all times. I bought some for others, and they loved this as well. There are cheaper files out there, but I haven’t been able to compare. So far this file has lost none of it’s Crystal "grit" – it does not scratch off.

Judith Nuremberg, PA

This is my go to file now.

It comes in a convenient holder so you don’t risk breaking the file. This is my go to file now. I’m thinking of buying one to keep in my purse also.

Glenna Morton Grove, IL

My precious

My file is in it’s case and with me all the time. It is the best glass file I have ever bought, and I have tried quite a few. Love that it is ground on both sides, that is a real plus. I take it with me when I get my nails done and have them use it. Nothing makes my nails feel as smooth and snag free as this file. I will never buy any other. I am going to buy these as gifts for my friends. Really top quality and if you keep it in its case, it will not break.

Beverly Knox City, MO

You won’t go back to cheap cardboard nail files

Great quality, easy on the eye, washable and very easy on your nails. It is glass, so it can break if dropped, but it comes with a plastic case to put it away in.

Jesse Dorchester, NJ

Good file

I was one of those people that bought the Revlon glass file at the drugstore after hearing about glass files. What a mistake and waste of money. So after that whole situation, I came on here to find a quality file. This one was just like OPI’s glass file only OPI’s comes in a plastic tube while this one is colorful and comes in a sleeve just like Revlon’s AND also another larger purple plastic tube case. This is the one I always keep in my purse; since the plastic case is colorful and larger it’s easy to find. They are both the same length. This file works very well and has really prevented nail breakage of any sort.

Very cool, much better than a regular file

I overheard one of my coworkers discussing nail files, and the fact that regular emery boards most people use are terrible for your nails. She mentioned "crystal" files as being much better. So obviously I did a quick search on Amazon and stumbled upon this product. I don’t tend to get my nails done at salons very often, so I figured this might be a good investment for doing my own nails.I’m shocked at how much I love this nail file. You have to be more careful with it (it is glass) but overall it’s much gentler on my nails, giving me a smoother file. I definitely won’t be going back to using regular cheap nail files.

Love this. Comes with sleeve and case. Good quality of material. Price was higher than most. It is an unique item.

Lora Sumner, TX

crystal file with case

i happen to be fond of crystal glass nail files.. they’re much easier on nails than any other kind of file. i like the case. it makes it much easier to carry the file wit me.

Lakisha Santa, ID

Excellent file

This is a excellent file, the color is pretty too. The case is nice, but it’s a little short for the plastic sheath the file comes in, bends the top. It certainly will protect the file though.

Crystal Glass Nail File

Love this Nail file. So smooth and easy to use on your nails. Will never use anything else. Nothing compares to this one.

For men too, m’kay?

I didn’t know what brand this was when I bought it, so I couldn’t pick the colors. As a male, I have a weird idiosyncrasy in plucking the hairs on my hand, so I’ve developed a habit of having perfectly trimmed nails to aid the process.But where my habit ceases, I’ve grown quite fond of having my nails neatly trimmed. It actually helps me think better, if that makes any sense whatsoever. So when my Revlon trimmer broke and my wife didn’t have any extras, I decided to go my usual route of researching and purchasing a replacement product: Amazon. This filer was the highest rated product, and, having not heard of glass filers before, I thought to try it out. A month later and and I can’t go back to the previous trimmers.See, I had to buy a filer because the highest rated trimmers didn’t come with any built in, but now I’d recommend this one over any built-in one. Albeit the lack of color options, I’m satisfied with it, my nails are coming out firmer (the sounds are louder when I roll my fingertips on a desk), and the file is easy to clean, coming with a case as well.

Noelle Wanda, MN

Love it!

Awesome file! Leaves nails smooth and works well without having to press hard. The colors are super cute and the case isn’t bad.. And it was on my doorstep in 3 days. I’ll be buying more!

Pearlie Los Ojos, NM


I love this thing! I use it almost in a daily basis. its so easy to use too. great product!

Jeannine Mahanoy Plane, PA

Really surprising!

Should you buy it: Definitely. Do it.Pros: It files wellCons: Word on the street is that it’s fragileI’ll admit it… I saw “Crystal Nail File” and thought, “really? But metal is so much more effective!” It had a lot of good reviews, so I checked them out, just to see what the fuss was about. There was a general theme of “It’s super effective!”, so I figured why not? It’s only $7.It’s a good thing I didn’t make a bet with anyone, because I would have lost that bet instantly. This thing IS really effective. It doesn’t look like it, because it looks like plastic, and it doesn’t feel like it, because it feels like sand blasted glass. But you start filing at your nails… and you can instantly tell that this is a quality product. It used to take me ~5 minutes to file my nails, but it’s more like 2 minutes with this. And I still can’t believe something that feels this smooth (unlike my super-rough metal file) works so well.The one thing I don’t like is that it will occasionally snag on one of my nails. It doesn’t hurt or anything, it’s just that I’m not expecting it since I file my nails as a fidget and it totally throws off my focus. Definitely not worth docking a star from a truly excellent product.

It is silly to be so enthusiastic about a nail file – I need a life! But I have never had a file like this. It is fine but works fast with few strokes. It leaves the nail edge extremely smooth. I don’t exactly know how to describe it, but of all the files I’ve had of all types, this is the only one I will ever buy again. When I purchased this I think I bought three – wish I’d bought more to give as gifts. Just perfect.
