The Utillian 5 Heating Chamber is an exact copy of the original chamber top of the Utillian 5 wax pen without the battery. Perfect for those who already own a box mod and just want a 510 threaded wax attachment. This new design of the Utillian 5 Heating Chamber now doubles as a loading tool and splashguard that can be integrated into your wax pen setup for quick and easy loading even when on the move. It is compatible with 510 threaded mods and requires at least 20W of power. Please note: Triple titanium or Twisted Kanthal coils are not included.
