【Wi&Fi Bass Clarinet New/Unused Item】Bass Clarinet Mouthpiece B5 Model

This is the Wi&Fi bass clarinet mouthpiece, B5, manufactured by a Taiwanese clarinetist.
Purchased new last week and used only on the day of purchase, it is in a condition that is as close to new as you would find in a store.

Facing length: L, Opening: 2.15mm

It produced a thick, clear tone with an easy blowing feel, similar to a combination of Selmer Concept and Vandoren B40. A blue box #3 reed fit perfectly.
There are few retailers, and the lowest price is around ¥22,000.
I cannot offer a significant discount, but please take this opportunity to purchase it if you are looking to try it at a lower price.

Below is the manufacturer's description.
Using the new material *V-Quartz, we have achieved excellent sound projection, tonal consistency, and a brilliant contour.
*A material hardened with quartz. It features high hardness and heat resistance. The tone is slightly darker than conventional ebonite (vulcanized rubber) mouthpieces. Since there is no tarnishing of keys (silver products) due to sulfur, it can be stored in the case with the instrument.
