This is a Nintendo wireless microphone. I purchased several of these for use at events, but they are no longer needed, so I am selling them. I have a total of 6, and discounts are available for multiple purchases. Please feel free to inquire. Originally sold as the "Wii U Wireless Microphone" for the Wii U, it has the same specifications as the current "Nintendo USB Wireless Microphone" for the Switch, so it can also be used with the Switch (according to official information). The main body shows some minor dirt from use. The USB receiver has some small scratches. The included accessory is the USB receiver. Mic No. AMZ463
