Review: High quality - Wow. I mean wow. I wasn't sure about this file but it proved me wrong. It filed my natural nails effortlessly and did break them. I have thin nails and this was gentle yet effective, very fine grain, my nails were smooth in a couple of goes. I imagine someone with thicker nails will take a but longer, but I see this nail file will work for all types of nails, natural and synthetic. Review: Brilliant and easy to use! - Wow! I'd never heard of Czech glass nail files before. I was searching for an enamel one when this one popped up on my search. I then googled "Czech glass nail files," and read all about them and found several websites with dozens of glowing reports, with not one complaint! So I took the bull by the horns and came back to desertcart and ordered this one - tbh, it was hard to choose which colour, maybe I'll buy one of each eventually, one for each room! This glass nail file makes filing fingernails an absolute doddle - it just glides so smoothly, you only need one swipe, not several like a normal emery board or metal file. Then all you have to do is hold it under a running tap for a few seconds, leave it on the side to air dry, and voilà! It's good to go again, or store it back in its lovely hard case. My sister has very hard big toenails that normally the podiatrist has to tackle, but I sent her a glass file and she said it's brilliant and easy to do herself now. I definitely recommend you buy one. It won't disappoint. (And while I'm here, let me also recommend the Czech glass foot file. Also much easier and better than a pumice stone.) ## Features - Genuine Czech Glass Nail File - a Bona Fide Beauty nail file for natural nails. Also known as a crystal nail file, this clear glass fingernail file can be used regularly to achieve strong and healthy nails. This nail filer is suitable for all nail types (thin, sensitive, thick, and more). - Salon Quality Nail Files - this Czech glass file feels luxurious and is comfortable to use on your own fingernails. Bona Fide Beauty Czech glass nail filers are the real deal! Made from real "Bohemian" crystal glass and manufactured in the Czech Republic. Achieve the salon experience from home! - Trim, Smooth and Shape with Nano Glass Nail Files - unlike other nail files, Czech glass files can be used in both directions. Expertly trim and shape natural nails with comfort and efficiency. Start with a light pressure when first filing your nails, and increase pressure as you feel comfortable. With every filing, the nails edges become sealed and smooth. - Durable, Long-Lasting, Reusable Czech Glass Files - Bona Fide Beauty nail files are tempered (strengthened) so that this manicure tool will last a longer period of time. The high grit is part of the nail file body and is not sprayed on. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09X6595VN | | Best Sellers Rank | 4,241 in Beauty ( See Top 100 in Beauty ) 29 in Nail Files & Buffers | | Brand | Bona Fide Beauty | | Brand Name | Bona Fide Beauty | | Colour | Clear | | Country Of Origin | Czech Republic | | Customer Reviews | 4.6 out of 5 stars 26,914 Reviews | | Global Trade Identification Number | 00850003137308 | | Grit Size | 180/240 Grit | | Grit Type | Fine | | Grit type | Fine | | Item Dimensions L x W | 10L x 10W millimetres | | Manufacturer | Bona Fide Beauty | | Manufacturer Part Number | SKU-B17-EUR | | Material | Glass | | Material Type | Glass | | Model Name | Glas-Nagelfeile | | Model Number | SKU-B17-EUR | | Model name | Glas-Nagelfeile | | Unit Count | 1.0 count | | Unit count | 1.0 count | ## Product Details - **Brand:** Bona Fide Beauty - **Colour:** Clear - **Grit type:** Fine - **Material:** Glass - **Model name:** Glas-Nagelfeile ## Images ![Bona Fide Beauty Czech Glass Nail File for Natural Nails, Single Crystal Nail File with Hardcase.

As you probably know, the different grit levels in nail files are similar to those of sandpaper, i.e. the higher the number the smoother the file (or the number of pieces of grit per square inch). Grit is an ideal measurement for determining the roughness of metal and paper files. However, the roughness of Czech Glass Files cannot be easily compared with the roughness of paper or metal files. They are completely different surfaces. The main difference is that paper or metal files have grinding grains attached to the surface of the file, while glass files have grinding elements formed right out of the surface of the glass body. We classify our Nail Files as Fine - Medium Grit, so they probably fall in the 240 - 180 grit category. They have a higher grit then most emery boards, but a lower grit then metal files, which are generally quite coarse.The main thing when choosing a nail file is to make sure it's not too rough & therefore damaging on the natural nail. When in doubt, it's always better to err on the side of caution and go with a higher grit or smoother file. You can also use Czech Glass Nail File alongside other files if needed. For thick or difficult nails, you can use a metal file or paper file (although, we do not recommend using these for long lengths of time as they can damage the natural nail) and use a Glass Nail File to smooth the nail edge, for a beautiful finishing touch. It all depends on your nails, whether they are thick or thin, healthy or frail, and what suits your needs. At Bona Fide Beauty we believe in supplying our customers with gentle nail care tools and do our best to avoid anything that causes damage or harm to the natural nail.The fine grit of Czech Glass Nail Files makes them an ideal nail care tool for shaping the free edge of the nail and for smoothing out bumps & dis-colorations. It is gentle on the natural nail and can therefore be used regularly - even daily. Unlike Metal or Paper files, the surface of the Glass Nail File is designed to file in a backwards & forwards motion without damaging the nail or tearing the keratin layers. It effectively seals the keratin layers in the nail, leaving your nails smooth & healthy and avoids shredding them like harsher files can do. It can also be used on artificial nails, we recommend when doing this to regularly wet the nail file with water for optimal results.I hope that helps you out. Thanks for reaching out :)Kind Regards, Jess @ BFB.FYI, some info on Grit:500 grit - is soft and normally is only used to polish the nail itself and not for shaping/filing240 grit - an ideal grit for buffing natural nails to a smooth finish or buffing away stains. It is also recommended for use on fragile, weak or damaged nails180 grit - the lowest grit appropriate for natural nails. Good for filing both finger and toenails down and into your desired shape, however if you have weak or damaged nails then you should probably try a finer grit100 grit - less coarse than 80 grit but should still NOT be used on natural nails only on acrylics80 grit - very coarse and should never be used on the natural nail as it is far too rough! A file this coarse should only be used on artificial nails, but even then proceed with caution. **Q: Does this work on acrylic nails?** A: BFB's Czech Glass Nail Files are suitable for use with both natural and artificial nails, however when filing artificial nails it is recommended that the file is dipped in water before and periodically during use. **Q: I use the emery board nail files but they wear out quickly. Do your glass nail files wear out quickly as well?** A: Not at all. Love it. I read some feedbacks stating to be sure to always file in one direction which is pretty standard, but very important for this files use. I don't think you will be disappointed for the price. Will last a lot longer than the emery boards which I also have a large variety supply and will still use for certain types of care. **Q: I'm a classical guitarist. I bought this file and like it very much for shaping, but does Bona Fide make a file with very fine grit for buffing?** A: Thank you for your question! We are glad you have been enjoying your BFB Nail File so far, that is great to hear :) Bona Fide Beauty's Czech Glass Manicure Nail Files are classified as Fine to Medium Grit. It is gentle on the natural nails and is the optimum grit for regular, long-term use. Unfortunately, this is the finest grit we offer in terms of Medium Manicure Nail Files. It's main function is to file and shape the nail. The grit seems to suit the general `bell-curve' of nails, however, if you are finding it too harsh, we recommend wetting the file by dipping it in water or rinsing it, to `dull' it slightly.Also, we offer Baby Nail Files which have a very fine grit:https://www.amazon.com/dp/B01B5VJTW2?th=1Even though these are `Baby Nail Files' they are great for adult use, if you don't mind the cute designs. They also come in protective silver plastic hard cases, so you can easily store one in your Guitar Bag incase you need to fix a jagged nail prior to a gig.You can also investigate a soft buffer block (there are many good quality ones available on Amazon or Walmart) for the purpose of Buffing & Polishing the nail. If you contact us via Amazon.com we can help you with some suggestions :) Please do, we would love to discuss this with your further.Kind Regards, Jess @ BFB. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality *by E***R on 20 October 2025* Wow.
