100% Pure Quartz
What in the world is coming off of that nail?! That my friends is a recycling tube.
Lets break this down: As the material melts down through the diamond knot INSERT the oil is flash vaporized. Any oil that did not get turned to smoke will run to the bottom of the bucket to be recycled back on top of the insert. Each kit includes one long nozzle bubble cap to help the air flow push the puddle of oil through the loop, as well as one diamond knot insert, which is removable for ease of cleaning.
*This nail would be best used for Low temp. consumption.
