Tweezerman Filemate - Filemate Geometric #sephora I can't say much more than what other reviewers have ready said, but I can try. I bought this inside a Sephora store, impulse buy (not because of online reviewers.). It seemed rather overpriced for a simple nail file. I needed an anti-testosterone "fix". One side was surprisingly rougher, maybe for toes, calluses, or gels/acrylic tips? I would have liked a wider choice of colors & patterns.
