Yonex Badminton Shuttlecocks Aerosensa 500 (some 600 mixed in) Used, 120 balls The box is for 600. Used in the circle I belong to. Used for games and basic practice. Some can be used for basic practice. Basically for knocking. Some have one feather missing, some have 1-3 feathers broken or frayed. Some feathers are not broken. (Please check the condition of the feathers in the photos.) The feathers have been neatly arranged and are ready to use. 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 in a box for shipping. Thank you for your consideration. I'm sorry, but please refrain from price negotiations.
