This is a set of Pokémon game cartridges. All cartridges have stains, erased names, or names written on them. I have confirmed that all of them work. The green cartridge is difficult to read. It reads after being inserted and removed several times. These are old items, so I cannot guarantee the backup function. Please refrain from purchasing if you are concerned about the condition. No individual sales or price reductions, please. Pokémon Game Boy
