This is a Nintendo GameCube memory card, official Nintendo brand, 59 blocks, and the standard gray color. Since it's official Nintendo, you can use it with confidence. It can also be used without issue on the Wii when playing GameCube software. I have confirmed its operation on my GameCube and deleted the data, so you can use it immediately upon arrival. Please note that there may be some minor scratches and signs of use. It will be shipped via Yu-Yu Mercari service with anonymous shipping and a tracking number. If you are paying via convenience store payment, please let me know the payment date and time before or after your purchase. If you have no questions when purchasing, you do not need to comment, so please purchase as is. I will handle the transaction with sincerity and care until it is complete. Thank you very much (^-^) #GC #GameCube #Wii #MemoryCard #Nintendo #Nintendo
