This is a set of 2 new, official Sanrio licensed genuine Bonbon Drop Seals, a Korean limited edition. As these are Korean limited edition items officially certified by Sanrio, they have a hologram sticker on the back as proof of authenticity. Naturally, the seals themselves are elastic and of a different quality than counterfeit products. For reference, counterfeit products can be identified by things like them collapsing when pressed with a finger, or lacking a hologram sticker. (Genuine Japanese products do not have hologram stickers.) I purchased these in Myeongdong, Korea for 8,000 won (approximately 850 yen per sheet at the exchange rate of the day). Therefore, including Mercari's fees and shipping, this is being sold at cost. I happened to see on the news that people who wanted these couldn't get them, so I hope that even a small number of people who want them can obtain them this time. The characters are: 1 Kitty, 1 Kuromi, for a total of 2 sheets. That's all. If you are interested, please check my profile and consider it. Thank you.
