This is a Kamen Rider Lotte Gum wrapper sticker from the 1970s, and it's considered rare because it's still remaining. You remove the backing paper and rub the sticker onto the desired surface with your fingernail or something similar to transfer the image. (However, it's been a long time, so it's uncertain if it will still stick.) The edges of the sticker show traces of being stapled, and there is approximately 50 years of aging, but it has been stored long-term in a tin case. Returns are not accepted, so please assess the condition based on the photos. Type...Single card, 1 piece
