YAMAHA YCR-4330GS Bb Cornet with Genuine Hard Case

I am listing this item as I no longer use it.
Both the piston and tuning slide move without any issues.
There are no dents that I can see.
Thank you for your consideration.
The included Silent Brass is being offered as a free bonus, as I was unable to test its operation due to a lack of batteries.
