Tenor Bass Trombone Semi-Hard Case DAC Original Project "Sa-Si" NA-1. This case uses lightweight and durable fiberglass for the material. It's a 3-way case that can be used as a backpack or shoulder bag. By making all the cushions movable, it can accommodate most models, including axial flow valve trombones and German-made instruments with long slides. It also has ample storage space and a cleaning rod holder! This listing is for the case only. There are some scratches due to it being a used item, but there is no damage. Immediate purchase is welcome! We will sell to the first person who purchases, even if there are comments in progress. Thank you. It will be wrapped in bubble wrap and corrugated cardboard for shipping.
