This is a mix of shuttlecocks from brands like Yonex, Gosen, and Club Shuttle. These are used shuttlecocks, used for knocking practice. Most of them have 1-3 feathers broken. They can be used for hand-toss knocking practice and basic training in badminton. They can also be used for batting practice in baseball and softball. Shipping is included in the price. If you can pick them up directly in the Kansai region, I can discount the price by the shipping cost. I am also open to price negotiations, so feel free to comment! Thank you.
