This is a sticker, so it can be affixed to a passport. I do not smoke or own pets, so there are no concerns about hygiene or odor. [Product Overview] Osaka-Kansai Expo Luxembourg 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 anonymously via Yu-Packet Post Mini, which 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 appreciate it if you would take a look. 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.
