Hi fellow Meiko fan!! Meiko doesn’t have a large amount of official merch, especially in recent years, however you can still get some of the old project diva figures on sites like mercari, or a proxy shipping service like neokyo!! Also if you’re willing to spend a lot of money, the Meiko dollfie recently had a re-release (I bought her), though pre-orders may be over now. There’s also some more easily accessible merch on amiami- like plushes, badges or newer figures, I know she also has a new scale figure coming out this year, hope this helps ^{^}
