this review title is: foot destroyer and the content is: this seemed wonderfully effective as it quickly filed down my worst callusesuntil my toes started bleeding it is basically a very sharp cheese grater being sold as a foot file and so sharp that it makes clean slices that took a moment to start bleeding i will never risk my poor feet again and now it is hard for me to use my actual cheese grater without getting grossed out thinking about my bleeding feet.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
