Review title is Blades of Glory [SEP] When I was a little girl, I remember seeing a callus razor of my mothers, and wondered why anyone would use one. Now that I am past the age that she was at that time, I confess I found myself on the hunt for the perfect pedicure items for those of us prone to alligator feet! Forget the ped-egg, it stays sharp for about a minute. Real women use blades! Caution, go lightly the first time, and always on WELL SOAKED tootsies. Less is more, a bit of callus is supposed to on our feet. Turn the double edged blade around for the second foot, then toss it, never use more than once. Buying them like this is the cheapest way to go. These are great quality blades at a great price.
