This is a set of 8 stamps of the original Pokémon released in the 90s. I don't know the details, but here are the characters and details: Bandai 1997: - Rattata ⚠️ The lid has a Chansey coin stuck in it, so the lid doesn't close properly. Also, there is graffiti. - Machamp Bandai 1998: - Eevee Nintendo with figures: - Horsea - Kakuna ⚠️ A Sawk sticker is on the lid. - Omanyte - Arcanine - Cubone The ink can barely be used in all of them.
