Pokemon Center 2011 Halloween Pikachu, Tepig, Cofagrigus, Litwick, & Whimsicott post it memo tags. This set of post it notes was only sold at the Japan Pokemon Centers in September, 2011, for a very limited time during the Halloween promotion. They are called "Post It" notes in English. The set comes with 5 different Pokemon characters on small tabs of paper that you can stick to any surface as a reminder note, bookmark, or any other thing you want to use them for. Im not sure how many post it notes of each character there is, maybe 10 or so of each, but its hard to tell because the package is sealed.
