There's one under the cosplay section, and one in the lolita section of the site! I'm assuming that people here will probably want to get the lolita LP so I'll post about that? It's in the 'dress' section of the lolita heading. It's marked 'FUKU002' and is currently 5000円. Not sure how much it is in any other currency, but if it's anything like how they tend to mark up USD, I'd recommend purchasing the thing in JPY. The picture has a bunny, and it seems to be lolita specific, if the Japanese heading is accurate (it says 'gothic lolita lucky pack, 5000en) and they do have a description of the lucky pack inside the link, though I've no idea what the difference bodyline's "OPs" and "dresses" are, nor why they have 'sock1' and 'sock2.' But this does seem to guarantee that the buyers will get certain things in their bags! I'm not sure if I'll be buying, but this does seem interesting... Anyone else thinking about getting it?
EDIT: The lucky packs now come with sizes! Not sure if they actually came up with anything above L, but yay 'choice'? Also, they are supposedly available till the 10th Jan.
