150 used badminton shuttlecocks. (Feel free to negotiate the price.) The proceeds will be used to cover the shuttlecock costs for junior high school students. Some feathers are broken or damaged. Various brands mixed, including YONEX and Victor. Will be shipped in a cardboard box. Some shuttlecocks can still be used for normal badminton practice, but it might be difficult. They could be useful for junior players' hitting practice. Also suitable for toss and tee batting practice for those playing baseball or softball. Stored at home, so please understand. Thank you.
