The Timemore C2 Grinder is a great travel companion. Some plastic components, including the internal body, keep cost and weight down while maintaining excellent grind quality. Built with sharp steel burrs, a spring mechanism that locks the inner burr into position, and two ball bearings that hold the grind shaft in place. The handle connection also allows for an exceptionally precise grind and a smooth rotation. The grounds bin is lined with aluminum for greater durability and a static free grinding experience.
