Review (5/5): Buying it for over a decade
Using these for over a decade.
No nasty mold grows on these things if you hang to dry, it dries quickly. Throw it in the washing machine with the towels to ensure a good clean.
For the skin, you'll need to get used to it, but it scrubs the skin better than anything else on the market.
No, that don't last forever, so you'll need to replace.
