18mm Male Diamond Knot Banger

With a double stacked knot to separate oil through two layers, you’ll get maximum vaporization of your concentrates, with minimum reclaim escaping the bucket. The knots are thicker than the 2mm outer walls, meaning that they’ll retain heat for longer. Just drop your concentrate into the center well, and watch as it bubbles around the knots for more complete vaporization.The recessed bowl shape is designed for heat retention, durability and efficiency- never wasting product with or without a carb cap.
