An ingenious design allows you to store this little brush inside your mouthpiece, and the handle of the brush has a small plastic cone molded on it that will help protect the mouthpiece shank in the event of a fall to the floor. Made for tuba.
Protec's Trumpet Mouthpiece Protector Brush is uniquely designed to clear back bores while simultaneously protecting the end of the shank. By keeping the brush inside the mouthpiece after every use, the handle protects the end of the shank from dents. Exclusively from Protec.
