Cleaning brushes for wind instruments, especially trumpets. There are three types of brushes! ● Conical shape for cleaning the mouthpiece ● Barrel shape for cleaning short tubes ● Blue brush for cleaning long tubes The brushes are soft and durable, allowing you to clean your trumpet without causing damage. All instruments require some maintenance, but wind instruments are very delicate and require care before and after each practice session. Convenient for thorough cleaning by pulling through the internal tubes of the long tubes.
