The present invention relates to a badminton shuttlecock which comprises a base made of cork and 10-14 feathers attached to the base with a uniform spacing. The present invention provides a shuttlecock where the angle between the upper surface of the base and the outer circumferential surface of the feathers is 75° - 87°, so production costs are reduced and users strike the shuttlecock conveniently and easily. Despite the reduction of feathers, the shuttlecock has the same flying distance as conventional authorized shuttlecocks and the damage rate is sharply reduced. Therefore, users can enjoy badminton. |
