BRASS DESIGN Straight Mute for Trombone [Copper End]

This is a tenor-bass trombone that I am selling because I primarily use a bass trombone and no longer need it.
It has only been used a few times for practice and performances, so there are no visible scratches on the main body, and it is in beautiful condition.
The outer box has some scuffs from storage and transport, but this does not affect the main body.
The following is the product description from the sales page:

● Mute made with new material nylon carbon
● Achieves excellent responsiveness not found in metal mutes due to the adoption of new materials
● Soft and transparent muted sound, and a sharp and rich tone when played loudly
● Industry's first cork attachment system introduced
● Lightweight and highly durable due to the use of nylon carbon
● Design focused on ease of use
