YONEX Mevious 2000, Blue (Suitable temperature: 12-23 degrees Celsius) Nylon Set of 10, 6 shuttles per tube Total: 60 shuttles The feathers are damaged, and there may be some wobble in the flight. I don't think they can be used for games, but they should be fine for practice, physical education classes, or children's groups. I myself have been using water-fowl shuttles for many years, but you can practice well with nylon ones, and they seem to be more durable than water-fowl ones. Please feel free to contact me if you have any questions.
