This is a copy of the Game Boy game, Pocket Monsters Silver! The case for the game cartridge is missing, but the instruction manual and original inserts are included. I received this from a friend back then, but I never played it. I seem to recall that the mythical Pokémon (legendary Pokémon?) Celebi was in the box from the beginning. The Game Boy's LCD is faulty, so I haven't confirmed that it works, but I took good care of it, so it's in decent condition for its age. There are scratches on the corners of the box, but I think it's in good condition considering it's over 20 years old. The listed price is just a starting point, and I'll be gradually lowering it. If you're interested, please ask any questions you may have! Thank you very much! #PocketMonstersSilver #PocketMonsters #Pokemon #POKEMON
