This is a popular Marcus Bonna horn case for bell-cut horns. It can hold sheet music, a music stand, and mutes. It can hold two mouthpieces. The accessory compartment is also quite spacious, so you can store a tuner, oil, grease, pens, clothespins, screwdrivers, etc. The instrument is securely held with cushions and belts (there is one cushion). The bell case also has good cushioning. *The accessories are all shown in the photos. Shoulder straps, accessory pouches, etc. are not included.
