These double mesh coils are designed for use with the Freemax Mesh Pro Tank and have a resistance of 0.2ohms for best performance at 60-90w. Composed of two vertically-mounted coils, they feature a unique side-located port which allows e-liquid to spill inside the coil and saturate space between the two coil heads. This means that the area between the coils which is usually hard for the e-liquid to reach becomes fully saturated, enabling the coil to deliver consistently-smooth, pure flavour.
