Plastic Clear Clamshell Nintendo Game Boy Cart Protector Opaque Cases Set Of 5 Set of 5 plastic clamshell cartridge cases for Nintendo Game Boy games. These are not Nintendo OEM but they are OEM-Style. They're mostly see-through but slightly opaque. Note that one of them has a small black mark that seems to be embedded in the plastic. It's cosmetic, doesn't affect functionality at all. All are in very good shape. Shipped with recycled packaging. 🌎♻️📦
