Used Badminton Shuttlecocks Yonex New Official only 120 shuttlecocks. Roughly 56 or more are suitable for basic practice (with minor feather damage), the rest are for knock practice. The photos show the shuttlecocks sorted into good and bad condition. New Official shuttlecocks are durable, and they can still be used for badminton knock practice and even baseball batting practice. Many are still in good condition and can be used for basic badminton practice. This is just my opinion, but even the ones for knock practice are in good condition. The last three photos show the ones in worse condition. The number grades are a mix of 3 and 4. These are used items, so please understand that we cannot accept returns or complaints. Due to the nature of the product, the assessment of the shuttlecocks' condition varies from person to person. If you are particular about the quality of the shuttlecocks, please refrain from purchasing.
