300 used shuttlecocks. Used for children's knock practice, hand-tossing, and net play. I'm selling these shuttlecocks because I have too many. These are shuttlecocks that were used for basic practice, then for knock practice, hand-tossing, and net play. The manufacturer is "mostly Yonex." A few (a small number) from other manufacturers are mixed in. I think these are perfect for practice that causes significant shuttlecock damage, such as hand-tossed smashes.
