Our design is back, with an upgraded buildout!! The head is constructed out of 33 tubes stacked vertically then fused inside a thick exterior ring of quartz. To use the nail you torch the entire body evenly, then allow for proper cool down time. Once you lay your concentrates on they will immediately begin to vaporize. As the oil passes through the tubes, it immediately thins out, and vaporizes taking full advantage of the unsurpassed surface area. Caps are optional, and greatly depend on use of the dabber.
