※ Wooden hand coffee mill, Kalita Coarse, medium, and fine grinding can be adjusted by changing the position of the stopper hardware. ※ Condition: Used, in working order ※ Shipping: Letter Pack Express Will be packaged in two parts at the wooden section. - Brand: Kalita - Material: Wood - Features: Hand-cranked - Country of Manufacture: Taiwan ✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰ 《Reference》 The adjustment screw generally uses the "wedge-shaped (serrated) screw" under the handle to adjust the fineness (coarseness) of the grind. Turning clockwise (tightening) makes it finer, and counterclockwise (loosening) makes it coarser. It is easier to adjust by tightening the screw all the way and then loosening it slightly as a reference point (medium-fine grind). Thank you for viewing.
