303 - 4 Stage Grinder

The first non-stick herb grinder ever. A 4-piece grinder that was ahead of it's time. Find out how we did it using ceramic, and zero teflon.

The SLX that started it all


The SLX 303 4-piece grinder delivers years of engineering into the palm of your hand. We applied our technically advanced ceramic coating to the most ergonomic grinder in existence, perfectly combining form and function.


Note: We no longer manufacture V 1.0 (the 206 & 303). You may still find one on a shelf, so we have left these pages up - but check out the SLX 2.0 pages for our current product line.


The SLX 303 is designed to meet the expectations of the most demanding users. Weighing in at 6 ounces, it’s heavy enough resist being knocked over, yet light enough to travel with ease. Four sections with matching threads offer full customization - take the top off and use it as a two piece, or remove the screen section and use it to store ground material securely.


What's in a screen? More than you think.


We chose a screen to do one thing: ensure that only the highest quality pollen falls through. Many inferior grinders use a wider mesh in an attempt to make users believe their grinder collects more pollen - when in fact, it’s just letting other plant matter through.


Why a four stage grinder?

If you prefer the ultimate in ease of use, the 303 is for you. Just put your material in, and the perfectly sized holes will automatically drop the grind through to the second stage. No guessing whether it's too fine or too rough. The second stage includes a heavy-duty screen - optimally designed to collect only the finest pollen and leave everything else behind.
