Vandoren
B40 Profile 88
Clarinet Mouthpiece

Tip Opening - 1.195 mm (0.057 inches)
Med.-Long Facing

$60

The Vandoren description says of the B40:
"Same facing as the B45 [but] with a wider tip rail, it produces a compact and centered sound."

The B45 is described as follows:
"The universal mouthpiece. With an intermediate tip opening and a medium-long facing, it is appreciated by most clarinetists."

Additionally I already had a 2RV and 5JB in stock
