I never knew such a product existed until browsing around on Amazon looking for a replacement for a nail file I lost. I ordered three of these (one for each bathroom and one for my purse), partly because curiosity got the better of me. All of the rave reviews for this product are dead on. Filing my nails is no longer a chore I put off doing, and my nails are growing longer and stronger as a result. It was well worth the price to purchase the file with the protective case. (I wish the case were metal, but so far, it's done a great job of protecting the file I keep in my purse.) If you've never tried one of these files and are always nicking/breaking your nails like I am, spend the dough. Just a great product! Some of these babies are going to find their way to some Christmas stockings this year ...
