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 careful about early termination! These are used Aerosensa 500 shuttles. I think they might still be usable for knocking practice for students and juniors? As a bonus, I will also include some shuttles that can still be used for my side job of repairing shuttles and practicing patterns. There will be a total of 120 or more shuttles, and they will be shipped in a tube!
