I am also listing this on other flea market sites, so I will delete the listing when it is sold. It has been opened, but it is new and unused. Size (white backing card): 6.5 x 12.5 Due to being a foreign product, there may be scratches, scuffs, air bubbles, or stains. Please refrain from purchasing if you are nervous about this or if you are looking for a perfect item, as it is stored at home. Please remove the blue protective sheet when using. Stamp plates: 50 yen off for the second item and beyond! Please comment before purchasing ^_^
