Premium Construction & Materials
This Italian-made screw bell case is constructed using a combination of genuine leather and a synthetic textile originally developed for motorcycle seats. The result is a rugged, scuff-resistant, and weather-tough exterior that stands up to years of professional use. It features a comfortable ergonomic main handle along with a secondary top handle for convenient transport.
Strap Options
Included with the case is a set of heavy-duty padded backpack straps, secured with black steel hardware that’s built to last. A single shoulder strap can also be used if preferred.
Superior Interior Design
Inside, the case is lined with a soft, durable grey/olive long-loop velvet. Unlike open-cell foam interiors that attract dust and debris, this lining is easy to clean and maintain—just wipe or vacuum as needed. There’s no need for velcro foam blocks. The lid closes securely with two keyed latches—no zippers to fail—and the closure is smooth and nearly automatic when pressed shut.
