This is a Marcato Sophia series tuba, an original brand of Shimokura Musical Instruments. B♭ tuning Bell diameter: approximately 36 cm Height: approximately 85 cm There are no noticeable stains, scratches, or dents. Purchased in January 2023 at the Ochanomizu store of Shimokura Musical Instruments. The price was approximately 300,000 yen. Used once or twice a week for about six months, and then stored in its case. It has been regularly maintained, so it is in very clean condition. It seems to be discontinued now, so I don't have further details. Thank you for your understanding. As it is a compact tuba, it is suitable for students in brass bands, women, and beginners. A soft case is also available, but it was stored in a place where a smoker was present, so although I washed it as much as possible, the smell could not be completely removed. Therefore, the tuba is sold without the case. (If you would like the case, I will include it for free. The case is not specifically for Marcato, but it is a perfect fit.) Please note that I may be slow to respond to comments due to work commitments. Thank you for looking.
