Max Limited have announced a new set of accessories for the Nintendo Switch called Nintendo Switch Pocket Mini Case. They’re small keychains that can actually house your game cartridges.
Each Pocket Mini Case is a 1/3 scale version of a Switch game box. The box art has been faithfully recreated in miniature form and attached to a keychain. Each one can hold only a single cartridge. While the Pocket Mini Cases may not have the versatility of other portable storage solutions, they certainly look pretty stylish. At the moment, only five designs have been revealed, and they’re all for Nintendo published games: The Legend of Zelda: Breath of the Wild, Mario Kart 8 Deluxe, ARMS, Splatoon 2, and Super Mario Odyssey.
They will be available to purchase at Japanese retailers in April 2018. Your import game will have to be strong in order for you to nab of these in the West.
