Why You’ll Love It
The big diameter means fewer twists and faster prep for group sessions. Razor-sharp teeth create an even, fluffy grind for smooth pulls, while the screened lower chamber saves pollen for later—no extra steps required.
Pro Tips
- Tap the sides after grinding to help pollen fall through the screen.
- Brush the teeth and screen regularly; deep clean with warm water and mild soap, then dry completely.
- For storage, keep the lid on to preserve aroma between sessions.
Level up your toolkit with a spacious, low-effort grinder that’s built to last and easy to maintain.
