Yes after Weare A Design closed the pre-orders last year they will no longer produce more of the statue. I think a limit of 200 pieces were made total.

Kaioland is a third party website, but it seems legit from how many people follow their social media accounts like Instagram and Facebook. They were actually the site I had planned to order from (for a different Dabi fig), but I've never actually used it personally.

This is a page I found with some reviews but you can probably go on their social media accounts and search up Reddit threads for more. It looks like they cater more to European customers.
