YAMAHA trumpet YTR1310. The case shows noticeable stains. Please check the attached photos. The trumpet has some age-related stains. Please also check the attached photos. There are also some minor stains that are difficult to see in the photos, but they are not very noticeable. I have experience with musical instruments, and the trumpet itself is in good working order, with no sluggishness in the pistons, etc. It gives the impression of producing a soft and beautiful sound. However, please purchase with the understanding that this is a used item. ⭐️Cleaning Set Contents⭐️ ・Valve oil (approx. 80% remaining) ・Slide grease (plenty remaining) ・Mouthpiece brush ・Water sheet (unused) ・Cleaning swab (unused) ・Polishing gauze (unused) ・Yellow cloth ・Blue cloth (large) I will pack it carefully.
