The all new Herb-e 7 was in design for a year and 4 months. The all new reactor coil chamber will click out like a camera flash card. This insures easy cleaning and allows for future coil projects. The Reactor Coil is a unique reverse coil design. The Kanthol wire is dipped in ceramic and fired. This eliminated wire to wax combustion that has been the standard since inception of the e dab pen. As always with the Herb-e line you have multiple settings for heat. Green Herb-e is for cool vaping, Blue Herb-e is for medium vaping and red herb-e is for powerhouse vaping. Careful with this setting.
