Dr Dana Precision Glass Nail File


| /

Regular use of our Precision Glass Nail File strengthens and seals the nail’s keratin layer, to make nails more resistant to splitting, peeling, and breakage.

Designed for natural nails: Many nail files, including crystal, glass and traditional emery boards, are too abrasive for natural nails and can cause microscopic tears at the tip of the nail that lead to breakage, damage, and premature polish chipping. Natural nails—especially if they are delicate, damaged or fragile—require a completely different technology.

In the above image taken with a scanning electron microscope, you can observe the clear difference between a nail filed with a traditional emery board file and one filed with our Precision Glass Nail File. The nail filed with the Dr. Dana file is smooth, even, and free of damage. Our Nail File features a high-performing precision technology grit to gently shape and contour natural nails for a smooth edge. Even weak or brittle nails can be filed in any direction with no harm to the nail.

Nail strengthener: Regular use of our Precision Glass Nail File will strengthen the nail and result in LESS splitting, peeling, and breakage.

Longer-lasting manicure: Our glass file creates a smooth nail edge, which will minimize snags and allow nail polish to adhere better, last longer, and chip less.

Long-lasting and sanitary: The file’s nonporous, double-sided design never dulls and is naturally hygienic.

Travel-friendly: This glass file includes a protective carrying case for easy transport and storage.

Developed by a board-certified dermatologist: Dr. Dana Stern is the only dermatologist in the country who devotes her entire practice to nails—including diagnosis, treatment and surgery—and is a leading nail expert in the media. She is also the first dermatologist to develop a nail renewal system to improve the health of nails.

Climate Neutral: We know everything we do has an impact on the planet. With this in mind, the Dr. Dana brand is committed to measuring, reducing, and offsetting our carbon emissions to remain climate neutral.

 Directions: File dry, natural nails to desired length. After use, clean with water and allow to air dry.

Great File


I have been buying glass files for years and 99% of them don't last long without getting dull. I have been using this file for several months now and it still works as good as the day I got it. Bought 6 more to give as Christmas gifts.

Greatly Improved Fingernails

I purchased complete set & glass nail file. Must use weekly to receive best results The glass nail file is the best I've ever used & I've tried many products for these aging nails. I do wait 24 hours before using a nail strengthener. I will continue to purchase these as needed.

Easy to use and works great. My nails are thick and with the glass nail file it is easy to file them without a lot of effort and time
