I used to work with the guy who makes the Realdoll. I once asked him what the cleaning kit was, and he said it was a sponge on a stick.
The first model of Realdoll was cast from a mold of his girl friend.
He hired a bunch of his former co-workers to help him when he was starting out. One guy said he'd work for free, but he wanted a Realdoll, but torso only. They made fun of him and then he said he wanted to hang it from his ceiling and use it as a punching bag. Then we were all afraid of him.
