Ddung are 1/6 scale, right? (At least these knockoff heads are..)
At any rate, anyone into Ddung should check their local dollar stores for Pencil Toppers (of all things, I know) that are perfect 1/6 size knockoff heads. They're rooted only adequetely but could be rerooted quite easily. They come off the pencil extremely easily. Sorry for the lack of pictures, but I do not have ready access to a working camera at the moment--I will do my best to take pictures when I hybridize mine.
