As the title says, this is a cornet for sale. Reference URL: https://jp.yamaha.com/products/musical_instruments/winds/cornets/ycr-2330iii/index.html In addition to the cornet itself, the following accessories are included: Mouthpiece 11E4 Mouthpiece 14E Instrument hard case C-guard silver product tarnish prevention cover (purchased separately) → Thinking about it, this might not be necessary for this product. Valve oil Slide grease Polishing cloth Warranty (expired) Instruction manual Please refer to the following for mouthpieces: https://jp.yamaha.com/products/musical_instruments/winds/mouthpieces/cornets/additional_tab3433.html The reason for selling is: I needed it for a brass band concert and purchased it in October 2022, using it for about two months. However, I haven't had much opportunity to use it since then, so I'm selling it now. It's a Yamaha entry-level model, but I think you can enjoy the cornet's characteristic tone. It's also recommended for those starting an instrument, as it comes with a complete set. There is some wear and tear, but both the outside and inside of the main body are clean, I think. Please check the photos posted. The oil and grease on the pistons and slides have been removed. I would be happy if someone would take it over. The price is set at 30% off the list price.
