I used this for my child's practice. I bought various practice equipment, but I think this was the most useful from junior high school to high school. It has a three-barrel design for rapid firing. This is a used item, so the barrels are sun-faded. There are 53 shuttles, but please note that some of the feathers are damaged. The box, instruction manual, and AC adapter are included. Operation has been confirmed, so you can use it immediately upon arrival.
