Silent Brass System Yamaha Trumpet Cornet SB7-9

Purchased over 15 years ago.
I used this when it was difficult to practice playing the trumpet aloud.
However, I didn't use it very often, and only used it for about 1-2 years after purchasing it.
After that, it was stored in a closet.

The personal studio (the machine in the lower right of the first photo) has been tested and powers on.
Batteries are included, so I will mention with batteries in the product name when shipping.

*The instruction manual is not included.
Everything shown in the photos are the included accessories.
The strap has some signs of rust.
There appears to be a very small black hole at the insertion point of the mute (last photo).
I am unsure if this is original or a scratch from use.
The box has dirt and signs of wear.

I will pack it with bubble wrap and ship it in a reused bag via RakuRaku Mercari便 (Takkyubin).

For trumpet and cornet players, please consider this!
