Yonex Badminton Shuttlecocks Aerosensa 500 & 600 Quantity: 120 *Aerosensa 600 are also included. Used in badminton games, and then also used for some basic practice. They have some wear and tear, but are still perfectly usable for knock practice. Also suitable for use in baseball toss batting, etc. It's a waste to just throw them away, so I'm selling them at a bargain price. *Shipping will be in simple packaging.
