Used approximately 20 times, in excellent condition. Selling to organize my collection. This is a super convenient, versatile wireless machine that can change strokes from 4.2 to 2.4, suitable for 7 machines. It's like having 7 machines, each costing around 2500 yen. Includes an adapter that can also be used with RCA cords. Cords are not included. One battery is included in the main unit. When changing the stroke, it's recommended to stop the machine once before changing. Only for those who understand how to use it.
