Used shuttlecocks, 36 in total. All shuttlecocks are AEROSENSA 700. These are used shuttlecocks, so I think they can be used for knock practice, etc. The speed numbers are mixed. If you would like to know more about the condition of the shuttlecocks, please comment and I will add more photos. Please understand that there are individual differences in the judgment of the condition of the shuttlecocks, so please purchase only if you agree. Also, returns are not accepted, so please comment if you have any questions. Price negotiation is OK ⭕️
