Thank you for viewing. This is hand-grinding coffee mill ④, manufactured by Lucky Coffee Machine Co., Ltd. It grinds quietly and smoothly. The ground coffee beans are also consistent in size, which is satisfying (Personal opinion) How about it for a rich coffee time? There is some coffee bean residue. You can adjust the grind size with a screwdriver. I'll include the specifications for reference. (The specifications are not included with the product) My collection has grown, so I have decided to put this up for sale. I will sell it as is. Please make your judgment based on the photos. As this is an old item, I will sell it to someone who understands. Thank you.
