This is a Macaron Lover Charm of Sogo Osaka from IDOLiSH7. It's a very cute keychain featuring a pastel-colored King Pudding with Sogo's member color and musical symbols, designed in a macaron style. The back features a Kinako design, also in a lovely light pink color. It has been stored unopened, so I don't think there are any noticeable stains, but please be aware of this if you are concerned.
