Puku Puku Stickers Set of 2 3D Stickers Due to being made overseas, there may be dents in the stickers, imperfections or misprints, warping of the backing paper, or folds in the packaging. Unlike the Bonbon Drop stickers sold in Japan, the inside of these stickers is hollow. (They still have a good three-dimensional feel ☺︎) Please understand that these are overseas products.
