I went to the GOODY site and they show a lot of styles. I'm not really picky so any of those would do, but this one looked good to me.

As to the transmapping. it migth be a good question as to how a transmapped brush would react going thru transmapped hair. If I had to guess, I'd think this brush had about 120 pins in it. Maybe that would not be too many to do physically.

Thanks.
