I received these as a novelty item at the Chiikawa Land in Tokyo Station on June 9th! I'm not a fan of Momonga, so if you like them, please take them! It's a set of a can badge and stickers. Since it's not for sale, I think it's rare ( ˙˘˙)/ I'm also listing on other sites, so if there's a purchase overlap, please understand that I may have to cancel the transaction. m(_ _)m
