Yonex Badminton Shuttlecocks Aerosensa 500: 96 pieces Aerosensa 600: 24 pieces Used by the circle I participate in. Used for games and basic practice. Feathers are broken or frayed. Most have 1-4 feathers broken. (Please check the condition of the feathers in the photos.) The feathers have been tidied up. How about using them for baseball or softball toss and batting practice? I think you can also use them for basic practice like knocking. I would appreciate it if those who are okay with the quality of used goods would purchase them. The shuttlecocks will be put in tubes and then in a box (the box will be for the 600s) for shipping. Thank you for your consideration. Sorry, but please refrain from price negotiations.
