This listing is for a set of 12 buttons featuring the Pokémon "Chansey" from the Pokémon series. Please refer to the ruler in the photo for the button size. The manufacturing year is unknown as it is not specified, but these buttons are discontinued and likely difficult to find in stores. They were originally in a bag, which was opened for photography and unfortunately tore. They will be shipped in a different bag. Thanks to the original bag, there appears to be no significant damage, but being old, there may be unseen damage. (The backing card has damage such as discoloration and folds). To avoid any issues, those concerned about the condition should refrain from purchasing.
