I think at least some of the vendors did ask permission to use Kozaburo's hair - they state so in the ads. (I'd hate to think they lied about it!) With the Gypsy hair, you can tweak the TFly settings so the hair looks right. Left at default, the wisps look like they're floating above the head, but moving them down a bit fixes that problem. (.3 to .5) I really like the Gypsy hair, myself. Neftis' hair is less malleable than many hair products, but definitely worth the sale price. (Guess where my money went today?)
