Loved these!
Bought these for myself. Both had different sized bubbles and we're completely unique (exactly what you'd expect from a rock). Some other reviewers complained of these coming broken or breaking shortly after purchasing. Thus far, I have only opened one and have used it every single day in the shower and it has worked wonders for my feet, mainly my heels, which become dry and Crack badly. I love these, and for the price of two it was more than well worth it.
