This is a Nintendo game device, the "Monster Ball Plus," which can be used in conjunction with the game app "Pokémon GO" and the Nintendo Switch game software "Pokémon: Let's Go, Pikachu! / Eevee!" The white part of the Monster Ball is flashing pink when held down! Also, Mew's cry is heard!! I don't know the details, so I would appreciate it if you could judge from this information. I cannot answer questions about the contents of the data. Please check the attached photos for the condition before considering a purchase. Additional photos are also available. Please feel free to ask. Thank you for your consideration.
