From Protec:
"Traveling by air or your local club date is a breeze with the attached wheels and telescoping handle.
The Protec PB-301VAX trumpet combo case is the result of a yearlong design collaboration with the famed trumpeter, Mike Vax. After spending years on the road as a performer, Mike has learned first hand what features a professional musician needs and appreciates. With a compact exterior dimension of 22" x 12-1/2" x 9" inches, this trumpet case will comply with most airline regulations. The exterior pocket design holds sheet music and allows for secure attachment of the Protec M-400 Mute Bag (sold separately). Interior layout fits many musical instruments. One section of the case fits a Bb trumpet or C trumpet, and the second section of the case fits a flugelhorn, cornet, and a Eb/D trumpet or piccolo trumpet."
