With all my regular at-home manicures, it seems like my nail files go dull fast. Luckily, I now have the Revlon File N' Peel 6-in-1 File ($4) in my DIY kit. The dual-sided wonder is equipped with three layers, so all I have to do is simply peel away the used layer to reveal a fresh new one. Genius!
