Review (5/5): Best for the toughtest calluses!
I owned an older version of this and bought this as a replacement. The nice thing about this one is that it is curved in a way to prevent cutting too deep (if at all). The older one was angled differently and I had a few accidents with it. In any case, this is a great product, especially for tough calluses, and I mean tough! I have bad calluses on both large toes and on the feet area under the smallest toe. For decades, I've tried pedicures, razors but this one the only thing that worked. I highly recommend this for anyone needing to get rid of calluses in the privacy of your own home. Enjoy wearing flip flops again!
