Innokin iSub Plex3D Coil utilizes advanced 3D technology which can deliver a truly superior vape experience. It increases the heating area for achieving better flavor from e-liquids. Moreover, the Plex3D coil is heating faster at lower wattages for longer lasting vaping. The unique geometric design of the Plex3D coil creates capillary action to draw e-liquids across the coils more quickly and evenly. Faster wicking means better vaping and helps to eliminate dry-hits. It is compatible with all of isub series tanks.
