Pocket Monsters Advance Generation Anime Hero & Heroine Post Office Postcard Set!! - Design: Pokémon characters (Pikachu, Green, Satoshi, etc.) ※ Brand new, unused, but has been stored in a drawer for a long time, so there are faint brown stains on the back of the postcards, as shown in the front and back views. You can see them if you look closely. I've included a photo on the 4th page. It's a little difficult to see... Please refrain from purchasing if you are concerned. Thank you.
