The Marcus Bonna MB 3 Piston Trumpet Case holds a mixed set of three piston trumpets, with configurations for instruments in Bb, C, D, Eb, and F or for two trumpets and a piccolo. Adjustable EVA supports fasten with hook-and-loop material so the interior can be arranged around the specific instruments. 

Marcus Bonna also lists an alternative trumpet-and-flugelhorn arrangement for this model; confirm that configuration with us before ordering.

Contact Houghton Horns if you would like us to confirm the fit of your specific instruments.

This case is designed for piston trumpets. Please contact us to order a case for 3 rotary trumpets.

A front compartment stores sheet music and accessories. The case can be special ordered with a detachable sheet music bag for additional storage.

The case includes:

• 2 backpack straps

• 1 shoulder strap

• 1 mouthpiece pouch for three mouthpieces

• 1 foam bag with zipper for oil and accessories

• 1 identification tag

This case is small enough to meet carry-on restrictions for some but not all major US airlines. For U.S. or European flights, check the packed case's outside measurements and the operating airline's musical-instrument policy. Cabin carriage depends on safe stowage, aircraft layout, and available space.

Handmade in Brazil.
