【Wii U Wireless Microphone - Nintendo Genuine Product】 This is a set of 2 wireless microphones. Since I don't have an environment to test them, I'm selling them as junk, untested. I've checked that they power on with batteries inserted, but there is no receiver. Shipping will include measures to prevent water damage and shock, and will be sent in a Yu-Packet Plus dedicated box. Thank you for your understanding.
