NBL6216 NILS are feather training shuttlecocks with an EVA base. The basket in this model is made of duck feathers, which provides greater control over the trajectory of the shuttlecock's flight.

Feather shuttlecocks have aerodynamic properties that make the game more dynamic, while at the same time giving the player time to make a precise hit.

Feather shuttlecocks are intended for amateur and professional play.
