HIGH QUALITY GREAT VALUE! The Timemore C3 is a brilliant coffee hand grinder. Some plastic components, including the internal body, keep cost down while making this grinder lightweight and increasing the capacity! The dual-bearing stabilization in the C3 utilizes a reliable spring mechanism to lock the inner burr into position, and ball bearings to hold the grind shaft in place, to ensure you're not losing even a little bit of grind quality. The well-designed handle connection gives this grinder an exceptionally precise grind and a smooth turning handle with every rotation. Lastly, the new and improved grounds bin is made from aluminum for greater durability and a static free grinding experience.
