This is a cylindrical, portable electric coffee grinder with an adjustable grind size, featuring a wear-resistant ceramic core. I am selling this because I received another one as a gift shortly after purchasing this. Purchase Price: 7,200 yen Precise Grind Adjustment: The stepless knob allows for coarse grinding with counter-clockwise rotation and fine grinding with clockwise rotation. You can freely adjust the grind size to your preference and extraction style, satisfying various drinking preferences.
