These are used semi-shuttles, suitable for practice matches, etc. There are about 80 Aeronsensa 500 shuttles and about 50 other shuttles from brands like Yonex and A-WIN, totaling 130 shuttles. They have not been used for knocking practice. Please forgive any slight miscounts of the brands. Sales are on a first-come, first-served basis, but I am also open to discussing the price slightly, so feel free to contact me. Most of the shuttles have some degree of damage, such as slight bending or fraying, but the Yonex shuttles in particular are relatively high-grade, so the corks are firm and the feel when hitting is good. Even if they look clean in the photos, the shuttles are bent. Please check the photos and make your judgment. They will be sent without the top lid, directly in the tube, with the shipping label attached to the shuttle box. The brand on the tube and the shuttles inside are not necessarily the same. Please understand that these are used items before purchasing. Thank you.
