A surprise release, these stamps come in giant Pokéballs along with a bunch of hard candies! Like the Cookie Can Badges, these are a bit difficult to get due to the cost and how limited they can become after release. But no matter, just makes collecting more fun!

 

Normally there are Pokeball (Red) variants, and Masterball (purple) variants, and this stamp is the same. Purple is on its way to me now, actually!
