Game Boy

The Game Boy Soft Case is a storage bag for the console and cartridges, made from Belleseime, a Japanese polyester-and-nylon microfibre that resists dirt and cleans easily. It launched with the original Game Boy in 1989.

It is extremely rare. It was sold only in Japan in a very limited run, and as one of the few Game Boy accessories given its own DMG number (DMG-06), it sits in Nintendo's internal numbering alongside the console itself. For many collectors the Soft Case is the single hardest Game Boy accessory to find.
