High-quality badminton feather shuttlecocks, AEROSENSA700. I used these for serve practice. Two were damaged, so I removed them. 10 shuttlecocks remaining. Of the remaining 10, 8 are like new, and 2 have slight signs of use but are also like new. - Model Name: AEROSENSA700 - Brand: YONEX - Model Number: AS-700 Thank you for looking.
