These are缶バッジ (can badges) sold in collaboration with Famima (FamilyMart) in 2019 by Mafumafu. If sold separately, they will be sold for 200 yen each. Brand new, unopened. I am also selling many other singer-related goods on other pages. If you purchase them together with other items, a discount is possible. #anzu_singergoods Please feel free to ask if you have any questions.
