Thank you for viewing. This is a Nintendo-official GameCube controller adapter sold for the Wii U. Model number: WUP-028 I no longer have the GameCube controller, so I have not confirmed its operation. There are no noticeable stains. This is an auction for the adapter only. Due to the nature of used items, no claims or returns will be accepted. Please refrain from purchasing if you are overly concerned about condition. Thank you for your consideration.
