Colorful Sanrio character sticker set, including holographic designs. After purchase, I have stored them in sleeves and kept them in a dark place, so there are no noticeable stains or discoloration. However, please understand that these are personally stored items. I will package them with cardboard and bubble wrap and ship via Mercari delivery. I will use recycled cardboard. Returns are not accepted after purchase, so please ask any questions or express any concerns in the comments. Thank you for looking.
