For the doobie smoker who is never caught unprepared, allow us to introduce you to the High Roller Portable Grind & Pack. This ingenious device is made of durable polycarbonate to make sure it's tough and delivers a quality grind. There are three pieces: the grinder, the chute, and the cone holder on bottom. To use, simply remove the grinder and chute pieces to slide your 84mm cone into the holder. Next, put the top piece back on and add material to your grinder. The lid snaps on with its magnetic closure. Simply give the grinder and few twists and watch your material fall directly into your cone. Use the packer stick provided to tamp down the pre-roll to the desired compression before sliding the finished product down through the bottom.
