Purchased from an authorized dealer of Nonaka Boeki. I bought this for my daughter, who was in the elementary school brass band, to practice with. However, she quickly transitioned to a real cornet, so it wasn't used very often. I had my daughter, a highly skilled third-year junior high school student, try it out, and it produced a surprisingly authentic sound! How about this as a practice instrument for children just starting to play the cornet, as a starting point for children who want to learn the cornet, or as a fun instrument for adults? ■ Key: B♭ ■ Bore: 11.6mm ■ Bell: 120mm ■ Body Weight: 540g (excluding mouthpiece) ■ Includes original resin mouthpiece and case 【Reference Retail Price】 22,000 yen
