Review (5/5): The best you can buy! The best for your buck!
Best pumice stone I could find. With my type 2 diabetes foot care is very important. I've gone through multiple other products. Nothing works as well at exfoliating than these all natural stones.
Update 12/2016:
They last and last. I haven't had them wear down at all over the past several months. I use them daily in the shower. I just ordered more for Christmas stocking stuffers. Great product!
