For padding, they use both 1/2″ and 1/4″ dense foam as shock absorption material. All of the cases have leather handles.
The three largest cases (for the resonators and rail/center support pieces) are designed for one person to carry, with wheels on the bottom, a shoulder strap and a handle on the side; or two people to carry, with handles on each extreme end.
Their cases accommodate both the soloist and adjustable frame instruments. A standard Marimba One case set has eight cases.
