The ASHARIO MATTE GRINDER employs a rubber surface coating which feels better in the hand with more grip. High grade CNC aluminum material with sharp diamond-shaped teeth makes grinding herb seamless. ASHARIO reveals the Soft Touch Matte Limited Edition which is a more durable, strong but surprisingly soft model version of the ALUMINUM GRINDER. The smooth, dense material sits elegantly in your hand and feels comfortable next to the skin. Material: Aluminum, coating rubber. Size: D55mm*H48mm
