>>37890508I'd keep watching ebay for non-Chinese sellers or look into a Japanese middleman for Yahoo Auctions. If you can't find it on its own, you might be able to get one in a lot.
The series is called My Pokemon Collection, and because they're small and on-model, they're a little on the wonky side and many of them have pieces that are just glued on. They aren't old enough for the glue to decay.
I haven't followed the market on these, I've bought them for an average of $20 when they came out.
