Gleichheit 10-2 Clear Clarinet Mouthpiece

Glaesel mouthpiece, 10-2, clear.
Purchased less than 40,000 yen in a certain location in Tokyo about half a year ago.

Facing: 22mm
Opening: 1.28mm

Compared to the standard black one, it produces a lighter and more refined sound.
I think a relatively thin reed works well. I used it with V12 size 3 reeds.

I am selling this because I have started using a different mouthpiece as my main one.
