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 break it into a slim pocketable Storage Puck. Grind and Go with the GR8TR by Kannastör.
