This Review Title is Best nail files ever! and the content is: 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☺..There are other information for this review, one is This reviewer did purchase it and the other is 6 people think this review is helpful.
