Smooth, Shape & Strengthen Without Damage

Elevate your nail care routine with the Dr. Dana Precision Glass Nail File—a dermatologist-developed, professional-grade tool designed to shape nails safely while promoting long-term nail health. Unlike traditional emery boards that can cause microscopic tears and fraying, this high-tech glass file features precision-etched grit that gently contours the nail’s edge while sealing and strengthening the nail’s keratin layer.

Regular use of this file helps prevent common issues like splitting, peeling, and breakage, making it a must-have for anyone looking to grow stronger, healthier nails. Naturally hygienic and built to last, the file never dulls—so it’s not just a purchase, it’s a permanent part of your nail care toolkit. Slim and elegant, it fits perfectly in your makeup bag, desk drawer, or carry-on.

Whether you’re recovering from gels or just prioritizing clean, expert-backed nail health, this is the file your nails deserve.

Strengthens Nail Edges: Seals and reinforces the keratin layer to help prevent splitting and peeling.

Smooth & Gentle Filing: Precision grit shapes nails cleanly without tearing or fraying.

Naturally Hygienic: Non-porous glass resists bacteria buildup and is easy to clean.

Long-Lasting & Sustainable: Never dulls or wears out—made for repeated, eco-conscious use.

Dermatologist-Developed: Created by nail health expert Dr. Dana Stern for safe, science-backed results.

Travel-Friendly: Sleek and slim for on-the-go nail perfection anytime, anywhere.

File dry, natural nails to desired length and shape. You can safely file nails in any direction. After use, clean with water and allow to air dry.

    Great file

    My second time purchasing. I lost the first one I bought. Everyone should have one, or two. It files your nails perfectly. No more raggedy edges on my fingernails.

    Best Nail File Ever!

    I will never buy another Emory board now that I have a Dr. Dana precision nail file. I love it. I bought one each for my sisters, and they love it too.

    Outstanding Nail File!!

    I Love, Love, Love!! This Glass Nail File! I have never had a file that works like this and so quickly! My nails look so nice now. I love it so much that I have one at my home chair, in my car, by my bed, in my husband's car and his side of the bed and 2 extras just in case I lose one.

    Best file ever

    Been using for awhile, and still has plenty of grit. Just like new. Just a tip....don't try to pry something open with it. It broke. It's glass. I didn't think first. Still works great though!
