07/09/2025 Update: Due to the 50% import tariffs that have been imposed on products from Brazil, we cannot currently accept pre-orders on Marcus Bonna cases off our website. Please contact us at sales@houghtonhorns.com to discuss pricing and timing of a special order.

The MB-SD design successfully blends the protective qualities of a hard case with the convenience of a gig bag! It fits nearly any horn.

The detachable bell section is very sturdy and easily removable by zipper. It is light and travel-friendly and meets the carry-on requirements for almost any airline. The bell section can also be zippered off the body section, to fit the horn body underneath your seat, and the bell overhead.

The back, sides, and bell sections are hard, while the front layer around the pocket is soft. Designed for maximum protection with minimum weight.

Includes Marcus Bonna "Strap with Loop" backpack straps - made of polyester and leather, with metal passerby and D ring.

Small accessories can be stored inside the front pocket. Thin accessories, such as sheet music, can be stored inside the back pocket.

Measurements: 21 x 14.5 x 11 inches

Weight:  5.67 lb

The case includes:

• 2 backpack straps

• 1 mouthpiece pouch for three mouthpieces

• 1 identification tag

Is this the right Marcus Bonna case for my horn?
