The perfect grinder is here. The innovative ceramic nonstick coating found on every SLX grinder provides a smooth & clean grind with every effortless twist. The new V2.5 SLX grinder is the last grinder you'll ever need. The proprietary ceramic coating on all surfaces inside and out means no more sticking. The grinder surface is 100% non-toxic, FDA-approved ceramic coating - ZERO Teflon® or PTFE. 27 trapezoid-shaped teeth, each featuring four cutting edges, evenly shred your flower into an airy, multi-use grind that falls freely through the drop-through holes into the chamber below without pulverizing key plant components. The 4-piece design is perfect for pollen collection and storage of ground materials. The easily removable screen gives you options for how many chambers you utilize. Just ONE set of threads! Machined to the thousandth of an inch, you'll never deal with difficult, mangled threads. Ideal grind for rolling up or packing into glass for a smooth, even burn every time.
