Has anyone tried one of these? They are natural sponges that you use on the face and you don't need to use a cleanser. They look a bit weird and are hard, but once you soak them they become soft. I just bought one and it's like a mild buffer and there is a string attached to to so you can hang it up to dry. The only downside is that it is natural and breaks down, and so will only last a month or so. I've only just bought mine, and while I like it, I'm not sure whether it's cost effective.
