These are shuttlecocks for basic practice and pattern drills in badminton. They were used in game practice by a team of working adults, and we've collected the ones that are still usable. The main issues are feather fraying or 1-2 broken feathers. We've tried to exclude those with warped cores or reduced flight performance. We will send them in a tube containing 13 shuttlecocks, without a lid. Please leave a comment if you have any requests. Due to the price including shipping, we cannot offer significant discounts exceeding 1000 yen. These are semi-shuttles of New Official (Class 1 certified) size 3 and 4.
