These are shuttlecocks for basic practice and pattern drills in badminton. They were collected from a social team after being used in game practice, and 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. 13 shuttlecocks will be sent in a tube, so there is no lid. Please comment if you have any requests. Due to the price including shipping, significant discounts over 1000 yen are not possible. These are semi-shuttles, Aero Sensa 500, size 3 and 4. Please note that the durability is inferior compared to New Official or 700. There may be a few Aero Sensa 600 mixed in. If sold individually, I'm considering selling 10 dozen for 14,000 yen.
