Being unaware that these even existed. I was very excited to try these due to skin build up on my feet. Didnt realize that my feet even looked bad but after using these i could tell a big difference in their apperance. Made my feet feel soft and the appearance was fantastic. Cant wait to purchase these for flip flop season. It did take awhile for my skin to shed off but once it started it was no time for them to look brand new. Just wish friends would of told me about these sooner!
