The iClear16 Dual Coil Clearomizer has TWO (dual coil) 2.1ohm heating coils - giving you maximum vapor production and great throat hits! Each clearomizer tube holds up to 1.6ml of e-Liquid.
Filling is easy. Just unscrew the mouthpiece and fill up the tank. Replacing the coil heads is a snap too. Simply twist off the old one and screw on another.
