Best nail files ever! [SEP] Best nail files ever! I have been a many decades long nail biter & am also hard on my hands in general. The thing that bugs me most is ragged edges & I've never found a file that truly smoothes out the edges to my OCD liking until now. They are well made & yes they're fragile but I am careful to keep them in their holders when not in use. Very, very pleased & I have fingernails now☺.
