The cartridge case allows you to store up to 24 game cartridges at once, making it easy to transport multiple games anywhere. The exterior is made from high-quality hard-type material, which is waterproof, dust-resistant, and shockproof, providing effective protection for the Nintendo Switch cartridge against bumps and drops. The case is also designed so that the cards do not press against each other. The cartridge case can store both Nintendo Switch game cards and SD cards.
