Ah...the original.
I had been using dupes for a while before my friend brought me the original from the US and I was in love.
Unlike the cheap alternatives from Dischem which can be quite hard, the original is light and fluffy. It expands quite a bit when it is wet but I don't use it wet, just a little damp.
My only issue with these products in general is that they are not easy to clean. I've seen some pretty disgusting makeup sponges in some makeup bags!!!
