These are puffy, glossy, three-dimensional stickers in the style of Bonbon Drop Seals, purchased from SHEIN. They are properly filled and do not dent. Please note that these are not Kuuria Bonbon Drop Seals. I ordered stickers from SHEIN, but the wrong product arrived, so I have duplicates to sell. The product was around 300 yen on SHEIN, so I think this is a pretty good deal.
