Badminton is divided into goose feathers, duck feathers, and parts of feathers. The best part is the feathers on the wings of goose feathers, which are described in professional terms. Then, no matter what kind of feather, the badminton is divided into full feather and half feather. Half feather is very common in low-end training balls, and there are variegated feathers, that is, the feathers are not bleached and the primary color is used directly.
If the ball holder is on the top, there are pure cork holder, semi-cork holder, and pure synthetic material holder. In order to adapt to different climates and altitudes, badminton is divided into several levels in terms of weight. We generally use 76, 77, 78 and 77 as the more conventional balls. In addition, there are all-nylon shuttlecocks without feathers that are purely recreational.
