Please refer to the past reviews for an evaluation of the shuttles. I am a PayPay user, so I primarily list on Yahoo! Auctions, but I list on Mercari after 24 hours! Please be aware of early termination! This is a used New Official shuttlecock. 18 pieces can barely fit in a Yu-packet Plus box. Each used shuttlecock has been inspected and repaired! It's a B rank (for pattern practice, basic training, etc.)! They can still be used!! Same-day shipping is available!
