Purchased from the official website last month. Used for only about an hour for instruction in a gymnasium. Instant purchase is welcome even during negotiation. The original box will be wrapped and shipped. ★★★★★★★★★★★★★★★★★★★★★ Instant purchase is OK, but please refrain from complaints after purchase, so please ask any questions you may have in the comments before purchasing. ★★★★★★★★★★★★★★★★★★★★★
