I've seen advertisements on YouTube from a company/brand named Mochipan, showing these moth cardigans. I'd really like to know if Mochipan is the original seller/designer, or if these come from some other, possibly smaller clothing maker, as I'd like to support the original designer/seller (whether or not it's Mochipan makes no difference to me - I just want to make sure I get these from the right place). Any help would be appreciated.
