This is a nice Vandoren CL4 mouthpiece for clarinet. The piece is in great shape showing just a little bit of light scratches and fading to the hard rubber. But no signs of major wear or past abuse. The facing profile of the table, tip and side rails is also in nice condition.
Vandoren made these pieces to play with a easy response, clear projection and even pitch. This one is used and can be picked up at a low price.
The tip opening on this mouthpiece measures .043”/1.092mm
