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 ^_^
