Please take a look as we have a large selection. Type: Shuttlecock Used shuttlecocks. There are 120 shuttlecocks. Mostly Yonex Aerosensa 400. Number 2: 1, Number 3: 9. Some are 600, 700, and some without numbers are mixed in. There may be a slight discrepancy in the number. Mainly for knock practice, but some are in good condition, so they can also be used for basic practice.
