I have already messaged some highly trusted stores that re-sell Pokemon merchandise (ones that I have already bought from and are reliable and trusted by many) inquiring if they will sell this merchandise and I am still waiting for a response from most of them.
I am almost sure none of these sellers live near the city of Yokohama. Fingers crossed they will sell the merchandise. The more options there is the better.
I think exclusive PC merchandise is not only the more limited but also always the best of any campaign.
Thank you for reading and for any information or help you provide.
