The patented RYOT Kannistor GR8TR Grinders offers the user an experience and variable grind unlike any grinder currently on the market. The GR8TR requires 50% less strength and torque making it easy to use for all! The aluminum version allows you to swap out the grinder plates and change the consistency of your grinds which is great for Vape use and traditional use. Additionally, there is extra herb storage in the lids and the GR8TR is modular like a transformer and can be broken down into several variations. Backed with a limited lifetime warranty, you won’t ever need any other grinder, because this does it all.
