Vandoren 5JB
Clarinet Mouthpiece

Tip opening - 1.47 mm (0.058 inches)
[ignore what I wrote on the label in the photo].

$65 for the mouthpiece.
Add $25 for the Vandoren nickel-plated ligature and metal cap.

There are some blemishes on the backside of the mouthpiece, but the tip, rails and chamber are like new.
This is Vandoren's largest tip opening clarinet mouthpiece.
The Vandoren catalog says: "The jazz mouthpiece."
They recommend a Vandoren Blue Box reed in the 1.5 - 2.0 range.
These mouthpieces are often used by sax players doubling on clarinet.
