The perfect for travel HARIO Coffee Mill Ceramic Slim is the smaller, lower capacity ceramic burr grinder from HARIO. Its thin, light construction and removable handle make it ideal for travel. The grind is fully adjustable via a locking nut on at the base of the burr (the bit that grinds the coffee), making it suitable for virtually any brew method, and coarseness is measured via clicks when turned. The burr set is kept more stable by a spring that sits on the shaft, leading to a more uniform grind.
