This is a ceramic hand coffee grinder that can be washed and disassembled. I purchased it at Nitori. I used it only once after purchasing it, but I am selling it because I no longer plan to buy coffee beans. The coarseness can be easily adjusted. - Product Name: Ceramic Coffee Mill - Features: Washable, Disassemble-able, Coarseness Adjustment, Easy to Hold - Size when stored: Approximately 10.5 x 7.5 x 19.6 cm Thank you for viewing.
