These sticker sheets are made of paper with a plastic coating, they'll last longer if not exposed to water.
Please note for the "Gem Friends" sticker sheet there was a manufacturer error where the Lapis Lazuli head sticker was not cut out. You'd have to cut it out manually if you want to use it!
"Ditto XD" is price reduced as the printing image quality is not as good
