This fascinating Amsterdam series of Grace Glass grinder comes with 6 pieces per display in mix colour. The 4-part grinder of 63mm diameter features a crank on the lid, for a handy grinding, and a window, for a cosy viewing. The magnetized lid fits securely the diamond teeth-shaped bottom through a nylon friction ring that facilitates the rotation. The screen will filter your herbs so as you can gather the remnants on the kief catcher bottom and reuse them.
