We are a custom shop based out of Phoenix, AZ specializing in quartz, titanium and hardwood All-in-one Enail Vaporizers. All of our units are cut and assembled with pride in the USA. We have a United States utility patent application on our innovative titanium heater cover. All of the metal used is pure Grade 2 titanium, selected for its superior heating properties. We have parts tested by a local minerals company, in a mass spectrometer machine. This completely incinerates the titanium, and ensures there are no dangerous metals present. For example, Grade 5 titanium and other alloys should never be used because of their levels of Aluminum and Vanadium.
