This is one unreleased sticker that came with the pediatric Tomiron fine granules from Toyama Chemical. It was distributed at pediatric clinics and pharmacies at the time. It is new and unused, but there are yellowing and stains due to aging, as it is a sticker from 1992. I have several of the same stickers in stock, so I will create a dedicated page. Please let me know how many you would like to purchase in the comments. Sanrio Heisei Retro Heisei 4 (1992) Keroppi Heisei Girls
