I purchased an assortment box from the official POPMART store on Rakuten as a gift for a friend, as I wanted multiple initials. (I've uploaded images 4 and 5, thinking they might serve as proof of purchase of the assortment box from POPMART.) The box will be shipped folded. The box isn't in perfect condition as my child opened it. Please be aware of this. If you don't need the box, I'll offer a 50 yen discount, so please let me know in the comments.
