Grinders play a major role in the dry herbal market, and they are often underestimated in their usefulness. Dry Herbal Vaporisers in particular, function optimally if the herbal material is ground/milled up first. There are 2 main factors that make them superior to scissors; the resulting herbal material is uniform in size and the surface area of each individual piece is increased. Both features work together to provide a more efficient vaping experience with minimal effort on your part. What should you look for? First you will need to choose between a Grinder or a Mill (this is a grinder that "shreds" herbal material). Materials used? Lastly, I would focus on design appeal as well as storage capacity.

Who are Kannastor? Kannastor has been making high quality Grinders since 2003, with a reputation of creating some of the most advanced designs on the planet today. A crack team of designers and engineers work tirelessly to ensure that all their grinders work at the highest possible level - no more stiff and squeaky grinders. This is their 5-Piece Grinder, part of their modular series of GR8TR grinders. The hallmark of GR8TR is the ability to swap out the grinding plates (2 are provided). This feature enables you to acheive either a medium or fine grind. Measuring in at 5cms in total height and 4.5cms in diameter this grinder is made entirely from super durable Aero-space grade 60/61 hardened (anodized) Aluminium. A highly functional and minimialistic grinder with no screen for kief collection along with a secret storage zone within the top lid. Lastly the bottom and top lids can thread together to form a storage puck for travel.
