This is a Kalita hand coffee mill. The model number is KH-5. I used this frequently and loved it a few years ago. I didn't wash it with water, but rather brushed it with a brush, so I think some coffee grounds may remain. Also, there are some scratches, so I would like to sell it to someone who understands that it is a used item. The price includes shipping, so I do not plan to offer a discount. Also, I may disassemble the top part slightly for shipping.
