The Pocket Ovens 4-Part Metal Grinder is built to tear up the contents into fine pieces with no messing about. With a diameter of 40mm and weighing only 33g, the Pengisar Metal Grinder is easier to fit in your storage boxes and smoking kits.

Simply open the magnetic top piece (lid) and fit in some material for grinding. Close the lid to start grinding, and the ground material will fall to the middle compartment. Unscrew the second compartment to get to your freshly ground goodies.
