This is a set of 46 pediatric stickers featuring Kero Kero Keroppi and Hello Kitty, a novelty item (not for sale) from Taisho Toyama Pharmaceutical. There are 23 Hello Kitty stickers and 23 Kero Kero Keroppi stickers. These are unused and have been stored in a box in a dark place. They are probably quite old. I will sell these to someone who understands that they have been stored at home for a long time.
