Yonex Badminton Shuttlecocks Aerosensa 500 (some 600 mixed in) Used 120 balls Used in the circle I belong to. Used for games and basic practice. Can be used for knocking. Some can also be used for basic practice. Some have one feather missing, 1-2 feathers broken, feathers broken, or frayed. Some 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 those who are okay with the quality of used goods will purchase them. The shuttlecocks will be put in a tube and shipped in a box. Thank you for your consideration. I'm sorry, but please refrain from price negotiations.
