Best practices Grind: Place your buds in the centre of the ashtray (keep that part ash-free). Take the cup-shaped storage vessel and place on top of the buds, crushing and twisting as you would a mortar and pestle. Store your ground flower in the cup once you’re done. Pack: Take your ground flower and place in the base of the cone-shaped pipe. Light when ready. Clean: Use rubbing alcohol or Higher Standards Supreme Cleaning Kit to remove resin build-up.
