The Hario Mini Mill Plus has a dark transparent look with the main improvement being the reinforced hexagonal adapter for the handy lock which makes the hand grinder sturdier than ever before. Apart from grinding the coffee beans you can also use the lower bowl of the Mini Mill PLUS to measure coffee grounds for up to 2 cups at a time (1 cup = 12g and 2 cups = 24g). The Mini Mill hand grinder Plus is perfect for travelling due to its compact size. Its extremely easy to dismantle which is why you will enjoy maintaining the manual grinder as much as the coffee grinding process itself.
