OK, I've just seen them over here for the first time.
1) What, actually, are they? They look like white sponges but come heavily overpackaged so it's hard to see.
2) Environmental credentials?
3) Do they work?
They're only four quid, so if it isn't concentrated bleach-and-ants in a bar or something equally nasty I'll probably give it a try. I remember other posters on here mentioning them, though, and thought I'd see what the consensus was.
