I purchased this from Kakaplanet. I put it away in a zipper bag after wearing it once. The wearing method is complex, so please refer to the included model photos. It's cool with various weapons as extras. I've confirmed it fits on an MDD, but the mask and hat are sized for 1/4 dolls, so they were too small to wear. (I managed to put on the mask with some effort.) There was also a silver hook-like thing that I didn't know how to use, but it was included from the beginning, so I'll include that too.
