Smooths, Shapes and Strengthens! 

Get ready to enter a world of nail care excellence with this Precision Glass Nail File. Developed by board-certified dermatologist Dr. Dana Stern, this innovative nail file is designed to provide you with healthier, stronger, and more beautiful nails. 

Our nail file features a high-performing precision technology grit to gently shape and contour natural nails for a smooth edge without the microscopic tears and damage caused by traditional emergy boards. It’s also naturally hygienic and never dulls, making it a one-time purchase (although you’ll likely want one for every bag!).

Regular use of our Precision Glass Nail File can lead to stronger, more resilient nails. It strengthens and seals the nail’s keratin layer, making your nails more resistant to splitting, peeling, and breakage.

Nail Strengthener: Seal and strengthen the nail's keratin layer, making nails more resistant to splitting and breaking.

Smooths: Precision Grit allows for a smooth edge without tearing the nail.

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.

    I wish I'd bought this sooner!

    Easy to use, my nails are much smoother than with emery boards

    Getting older is hard. Especially when you move and load and unload boxes, carry many heavy things, wash lots and basically lose any nail you had. My nails separated from the skin some and split and became soft and would easily be damaged. I'm being patient but started with the starter kit and religiously did as instructed, as I continue to wash and work with lots of boxes. I finally have nails again. They are still a bit vulnerable but it is a big change from a couple of months ago. So then I ordered the manicure set to have the glass nail file and oil to help with dryness, which is/was a major factor. I feel I will continue to progress and firm up my nails in spite of the abuse I'm inflicting on them with the help of Dr. Dana's manicure and starter kits. Thank you!

    They are the best nail files. Won't use any other. Purchased one for my granddaughter.

    As someone who does all of their nail care and manicures at home, this glass nail file is one of my favorite tools in my arsenal. It has just the right amount of grit to effectively file and shape natural nails. Yet, it is gentle enough so as not to promote striping and slitting. I get the smoothest edge with this file. No snags after use. I also find it sturdier than other glass files. I’ve managed to drop it a few times without breaking it. I highly recommend.
