Yonex Badminton Shuttlecocks Aerosensa 500 (Aerosensa 600 also included) Used 120 Shuttlecocks Used by the circle I participate in. Used for games and basic practice. Some can still be used for basic practice. Basically for knocking practice. Some have one feather missing, some have 1-3 feathers broken or frayed, and some feathers are broken. Some are not broken. (Please check the condition of the feathers in the photos.) The feathers have been neatly arranged. I hope that those who are okay with the quality of used goods will purchase them. The shuttlecocks will be put in a tube and then shipped in a box. Thank you for your consideration. Sorry, but please refrain from price negotiations.
