Once you try a Kannastor Grinder, you will understand why they are known as the world’s most advanced grinders. The brand has the most complete line of grinders offering a diverse range of sizes, colors, and styles. The multi-functional products work as a spice, herb, and tobacco grinders equally well. Kannastor grinders are made from high-quality food-grade aluminum and include a number of design features that set them apart and above the rest. The latest Kannastor collection features the GR8TR grinders which include interchangeable grinder plates so you can control the consistency of the grind between a more coarse smoking blend or a finer vaporizer shred. The GR8TR collection items are modular in design and can be configured as a 2,3, or 4 piece setup based on your needs.
