They come in various colours of course I got PINK.
You can use this dry or wet, I have tried both and found that using this dry works best on the heels but for removing stains then wet is best. I wouldn't say this is brilliant for removing or softening heels as well as my foot file but for a cheap alternative this is fine. Even if you don't use this for your dry/rough skin then this would be handy to have in your kitchen as a stain remover. This removes stubborn stains like grease, paint or dirt. I must admit I had a stain on my carpet and have been using it for household tasks rather than for my feet. I will be sticking to my foot file for my dry cracked heels.
Have you tried or seen this?
