Thank you for viewing. This is a hand coffee grinder ② manufactured by Lucky Coffee Machine Co., Ltd. It grinds quietly and smoothly. The ground coffee beans are also consistent in particle size, which is satisfying (personal opinion). How about enjoying a rich coffee time? There is some coffee bean residue. You can adjust the grind size with a screwdriver. I'm including the specifications for reference. (The specifications are not included with the product.) My collection has grown, so I'm putting this up for sale. I will sell it as is. Please make your judgment based on the photos. I will sell it to someone who understands that it is old. Thank you.
