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 flashcard. This ensures easy cleaning and allows for future coil projects. The Reactor Coil is a unique reverse coil design. The wire is dipped in ceramic and fired. This eliminated wire to wax combustion that has been the standard since the inception of the dab pen. As always with the Herb-e line, you have multiple settings for heat. Kangol  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.
