This is a rare CELLO & COO tuba, made by Kan! The pistons have been adjusted and it plays well! [Condition] There is some rust due to age, but there are no dents or other damage that would interfere with playing, and the lacquer is still in good condition, making it a relatively beautiful item. The pistons have been adjusted for sale. The slides move smoothly without sticking. This is a high-cost-performance model, so it sounds great, and I highly recommend it to those who are just starting to play the tuba. Accessories include a hard case. You don't often see items in this good condition, so please consider this opportunity! Please check the photos carefully. Although it is a good item, please understand that it is a used item before purchasing.
