Trombone Euphonium Practice Mute Embouchure Mouthpiece Practice

Thank you for looking at my listing among so many others!

This is a practice slim mouthpiece for trombone and euphonium! You can use it to check your embouchure or practice buzzing! ✴︎

I'm listing it because I received it but never used it ☆

It might seem a bit expensive, as music stores usually don't offer discounts on this item, but my friends all use it and say it's convenient!
