This little grinder is perfect for travel. Its sturdy stainless steel body is small and perfect to pack away. The handle can be detached and stored on the silicone band to make it even more compact. It features a quick adjustment screw for manipulating grind size on the fly. Most of our manual coffee grinders use burrs made of ceramic - conical ceramic burrs transfer less heat and shave coffee beans versus cracking them like blade grinders. This process also provides a more consistent grind that can easily be adjusted and set for repeat use.
