This is a limited edition "THE IDOLM@STER" premium kit released in 2005. It includes a 32-page booklet and two special rewritable cards, and was sold exclusively on the online store "Shop Inbound." Two rewritable cards (game memory cards) that can be used in Namco's arcade game "THE IDOLM@STER" are included. The cards can still be used in the game machines at arcades today. I also have other niche Idolm@ster goods for sale, so please take a look if you're interested.
