Heating element embedded in porous ceramic.
Universal 510 / M7 threaded fitting.
Heating element embedded in porous ceramic for even saturation and clean vapor.
Standard press-fit configuration with a full mouthpiece catalogue available.
The atomizer embeds the heating element in porous ceramic. Oil saturates the ceramic wick before reaching the coil for smooth, even vaporization.
