The Innokin iClear 30b is Innokin's newest version of the clearomizer design. It's a bottom dual coil clearomizer with a large capacity for liquid. This clearomizer is a perfect match for Innokin's Cool Fire and Cool Fire II mods for a finished polished look. One of the most appreciated upgrades for this model is the advanced replaceable bottom feeding dual coil head. The benefit of the bottom coil head is the constantly saturated wick so vapor production is quick!
