>>9138088Will add onto this because Muscuto's shop pictures are kinda overwhelming, you might want to look at his actual store page to get a clearer idea.
They're sold by this one guy in Japan twice a year, he recently took orders for these at the end of June for about a week and probably won't reopen until December. There's two styles of underwear, anon's photo is the cheaper at 5000 yen and the tri colour costing 6000, in assorted colour options and each come in two skin tones and finally there was the option to purchase only the torsos (so no chest or pelvis parts). I think the torsos are a pretty good deal now that these kits have official tops and bottoms.
>>9138227Don't mind if I rephrase this, it looks like you get (1) small, (1) medium and (1) large part of the boob that's exposed flesh, then you get each of the 3 underwear (so you can't display every colour from purchasing a single 6000 yen kit). If I read you right there's no way you get 6 boobs.
Pic rel is a bootleg of a previously sold kit, the ones that were sold last month will not come with thigh parts, tl;dr the new tri colour sets will be likely still be like this but with extra bra/panty runners only.
