The YONEX Mavis 300 Badminton Shuttlecocks come in 2 tubes of 6 shuttlecocks. YONEX draws on its long experience in feather shuttlecocks to design and manufacture nylon shuttlecocks that closely approximate feather shuttlecocks in recovery, peak and drop and flight trajectory. In smash-speed tests of up to 300kmph, a Yonex Nylon Shuttlecock demonstrates recovery in 0.020 sec. only 0.0005 sec. off the 0.015 sec. recovery performance of a Yonex Feather Shuttlecock. In addition to the ability to recover instantly, Mavis Nylon Shuttlecocks have a consistent peak and drop and highly accurate trajectory for full enjoyment during rallies.
