Sanrio Kero Kero Keroppi Stickers From 2002. I received these in the past and have stored them in a box in a dark place. There are some stains on the backing card, but the sticker surfaces are not particularly dirty. Please refrain from purchasing if you are concerned about minor imperfections. ☆ As for the packaging method, the item will be sandwiched between cardboard or similar thick paper on both sides, or placed in a hard case, and then placed in a bag to prevent water damage. ☆ Shipping will be via regular mail. If you have no questions, you can purchase it as is. Thank you very much.
