Aero Sensa 700, 20 dozen. These are badminton shuttlecocks for basic practice and pattern drills. They were used for game practice by a team of working adults, and I've collected the ones that are still usable. The main issues are feather fraying or 1-2 broken feathers. I've tried to exclude those with warped cores or reduced flight performance. They will be sent with 13 shuttlecocks per tube, so there are no lids. Please leave a comment if you have any requests. The price includes shipping, so I cannot offer a significant discount exceeding 1000 yen.
