I thank gawd that I'm not a "fan" of vocaloid merchandise. Whenever a new item comes out, it sure sold out as fast as a bush fire. I kid you not.
Anyways check out the latest Petite releasing in November this year. I'm skipping this coz I've already pre-order three (3) nendoroids for that particular month. *facepalming.
Heck! Even Animetsu doubled their stock XD
