UNIQUE FUNCTION FOR EASY OPEN & LOCKING | You won’t have to worry about the metal grinder’s main compartment getting stuck with the ONGROK 4 Piece Grinder’s quarter-turn function. Access to your herbs is now made easy. REMOVABLE SCREEN MAKES IT EASY TO CLEAN | A removable screen makes this grinder a breeze to clean. Lift the handle and turn it counter-clockwise to remove the screen. The ‘catch chamber’ can be used as a storage compartment when you’re on the move. PRODUCE THE PERFECT GRIND | Sculpted out of aircraft grade aluminium, this grinder utilises 33 triangular teeth for a medium-to-fine grind. You can count on this spice and herb grinder every time. LONGER TERM STORAGE WITH SMALL HUMIDITY PACKS | A 63mm diameter allows this spice grinder to be both compact enough to carry around, and roomy enough to fit a small/mini humidity pack in the bottom chamber.
