YONEX Mevious 2000, Green (Suitable temperature: 22-33°C) Nylon Set of 5, 6 shuttles per tube Total: 30 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 feather shuttles for many years, but you can practice well with nylon ones, and they seem to be more durable than water-fowl feathers. I also have the blue version for winter (suitable temperature: 12-23°C) for sale. I will offer a discount for purchasing both sets. Please feel free to contact me if you have any questions.
