This is a speed shuttle machine released by Field Force. It operates on batteries or AC power. I have confirmed its operation for this listing. Sometimes the shuttle doesn't come out, but this is not a malfunction; it's a characteristic of the product. It can be adjusted by how you insert the shuttle and the angle. The set includes the machine body, the shuttle loading tube, and 12 shuttles. AC power is not included. It will be packed in cardboard or cushioning material for shipping. It was only used indoors and infrequently, so it's still in good condition.
