Carry and protect a 000-size acoustic guitar in a shaped, black polyethylene hardshell enclosure sized for thinner-body instruments. The 1SKB-000 has an interior length of 40.5 inches, accommodates a 20-inch body length, and provides 5.75 inches of body-depth clearance. Its 15.5-inch lower-bout allowance suits the body geometry associated with many 000 acoustic guitars. Rigid EPS foam and a heavy plush interior cushion the instrument, while full-length neck support cradles the neck from body to headstock. That support is particularly relevant for guitars with a pronounced vintage V-neck profile. Molded-in exterior bumpers protect the case valance when the case is set down, and the cushioned rubber over-molded handle provides a secure carry point. Nylon trigger-release latches close the case, with built-in TSA-approved locking capability for checked travel. Unlike a general rectangular equipment case, this model uses a shaped acoustic-guitar interior and dedicated neck support rather than an open cavity. It is supplied empty, allowing the case to protect the compatible guitar without storage compartments or a pressure-purge valve.
