Key/Tuning: B♭ Bore: 14.5-16.8mm Bell: 310mm Weight: 2.0kg (excluding mouthpiece) Valve System: 4 pistons ⭐︎Includes original resin mouthpiece (photos 11-13) ⭐︎Soft case bag (can be used as a backpack) ⭐︎Instruction manual (wrinkled), valve oil included Manufacturer's Suggested Retail Price ¥73,700 (tax included) 〈Silver/Gold〉 (Silver and Gold have different prices than other colors.) Although it's a plastic instrument, the sound is bright and beautiful. My child used it for a short period as a student. It hasn't been used much, and I don't think there are any noticeable scratches or stains. There's only a slight sign of use inside when looking into the bell. (It tends to look black in the photos, but in reality, the silver color inside the bell is slightly dull.) I will clean it as much as possible before shipping. Euphoniums are often expensive and out of reach, but how about this one for beginners or students? ※In photos 1, 5, 6, 7, and 8, the outside of the bell appears dark, but in reality, it's a clean, single-tone silver color with no color boundaries. ※I apologize, but please refrain from purchasing this item if you have any "bad" ratings. ※I am also selling a euphonium strap (brass sling). Please take a look if you're interested♪
