The Groove 4-Piece Grinder from Aerospaced comes in several colors, and a multi-colored rasta. Instead of the traditional teeth found in most grinders, the Groove uses a “coaxial turbine” system that produces a coarser grind, and somehow keeps the bigger stems in the grinding chamber. The coarse grind works great with a vaporizer like the Firefly 2+. The top lid is magnetic, while the other chambers screw together. The 4-piece design has a grinding chamber, herb chamber, and a pollen chamber.

We have a full selection of grinders for all of our vaporizers.
