Vandoren B♭ Clarinet with Optimum Plastic Cap, Color: Black Finish

Accurate and quick tightening Unique double track screws tighten both sides of the ligatures evenly
Vertical, symmetrical tightening keeps the lead secure and the lead and ligatures are not pressed on the side.

There are three interchangeable pressure plates that can be matched to the sound, style and song playing. The collar around the mouthpiece is independent from where it meets the lead, so the vibration of the lead is not obstructed.
Black finish
