These are used semi-shuttles, suitable for practice matches, etc. There are a total of 120 Aerosensa 500 shuttles. They have not been used for knocking practice. Please be aware that there may be a slight mix of other brands. Sales are on a first-come, first-served basis, but we are open to bulk purchases and price negotiations, so please feel free to contact us. Most shuttles have some degree of breakage or fraying, but they are high-grade Yonex shuttles with solid corks, providing a good hitting feel. Even if they look clean in the photos, the shuttles are broken. Please refer to the photos to make your judgment. They will be sent in tubes with the lids on, and the shipping label will be affixed directly to the shuttle box. Please understand that these are used items before purchasing. Thank you for your understanding.
