This is a set of 12 buttons featuring Mew from the Pokémon series. Please refer to the ruler in the photo for the button size. The manufacturing year is unknown as it's not specified, but these are discontinued and likely difficult to find in stores. They were originally in a bag, which was opened for photography and has since torn. The buttons will be placed in a different bag for shipping. Thanks to the original packaging, there appears to be no significant damage, but being old, there may be unseen damage. (The backing card is crushed and in poor condition). To avoid any issues, please refrain from purchasing if you are concerned about the condition.
