This is a sticker, so it can be affixed to a passport. I don't smoke or have any pets, so there's no need to worry about hygiene or odors. [Product Overview] Osaka-Kansai Expo EARTHMART Label sticker, 1 sheet Remarks The label sticker is a firmly adhesive type purchased from a 100-yen shop. Please cut it to fit your passport before use. [Shipping] Shipping will be done via Yu-Packet Post Mini, which is anonymous and allows for tracking. If you are okay with regular mail (mini-letter), I will offer a 50-yen discount. I also have many other stamps for sale. I would be happy if you would take a look at them as well. Combined purchases are also possible. [Bundling] If you purchase multiple items at the same time, I will offer a 10% discount through a combined purchase request, so please contact me. Thank you.
