These are used semi-shuttles, suitable for basic practice. There are 12 Aeronsensa 600 shuttles and 84 Aeronsensa 500 shuttles, for a total of 96. They have not been used for knocking. I have checked them many times, but please understand that occasionally other brands may be mixed in. Most of the shuttles have broken feathers or fraying, about 0-1 feather per shuttle, but they are high-grade Yonex shuttles, so the corks are firm and the feel when hitting is good. Since they are not new, the category is "Slightly scratched or dirty." Some can be used for basic practice. Please take a look at the photos and make your judgment. They will be sent in a tube without the lid, with the shipping label attached directly to the cardboard box. There is no compatibility between the tube and the shuttle brand. Please understand that these are used items before purchasing. Thank you.
