Soft pack case for trombone by BAM, with sheet music storage pocket. This case uses reinforced ABS resin for excellent safety. The two-tone case has four surface colors, and the back is covered with vinyl leather, offering a fresh design compared to traditional cases. There's also space inside the case for small items like mouthpieces! The non-slip backing is outstanding, providing excellent instrument hold in this type of case. (From the homepage) I was using it to store a Getzen tenor bass trombone. Thank you for looking.
