Diamancel Luxury Diamond Nail File – #1 Fine Grit Finishing File for Fingernails

Q: This is authentic Diamancel product?

Pro-Merit is the exclusive distributor for genuine Diamancel files.

Q: Is the diamond finish only on one side?

The diamond finish is only on the front side of the file.

Q: What is the difference between the number one fine, number two medium and number three course filers? Which is the best?

I bought the number one fine because my nails were too fragile. It helped.

Q: Are these a solid ceramic type material, or steel with diamond coating? If made of something other than a steel base, is it fragile, easily broken?

My husband says these are stainless steel, but I don't know what the coating is. What I do know is that these are the best nail files I have ever owned. They are sturdy and I clean them with warm water and a dash of soap to keep them clean. I highly recommend these nail files. I won't use anything else ever since I found these!!!
