I have wrestled with me, whether I want to spend the money for it - after all, you get a trademark natural sponge for the same money in about double size. Klein is the Silk really, but it fits well in the hand, is almost round and has little deep dents (a bit like the picture). When unpacking I still thought "pretty little sponge" but the first wash, he appeared in the size a little baby neck :) pretty reasonable. He's really soft. I have no comparison with other natural sponges, but it is definitely much softer than a plastic sponge and has no hard inclusions or skeletal remains. When it is over, I'll probably order the same again.
Addendum: I now have the comparison with natural sponges. This is clearly fine-pored and very soft compared to other.
