GR8TR Grinder in Matte Black


The gold standard in smoking technology, the GR8TR Jar Body Grinder in Matte Black is perfect for vapes, pipes, one-hitters and more.



“Breakthrough design and technology. I have a grinder collection that most people would dream of, but the GR8TR is what I use every day,” OB Gold, Author of Seven Steps to Marijuana Mastery.


No other grinder is this versatile.


The GR8TR has it all, including both Vape and Standard Easy Change Grinder plates, a 60 Mesh Stainless steel Easy Change Screen, top lid bonus storage, and all the modularity that one could ever hope for.


Build It Your Way


The GR8TR is modular by design. When it comes to assembling and configuring your GR8TR, the choice is yours.


Not interested in sifting? Remove the sifting chamber to create a perfect 3pc GR8TR. Otherwise, convert your grinder into a storage sifter and get the most out of your herbs.


You can also brake it into a slim pocketable Storage Puck.


Grind and Go with the GR8TR from RYOT.
