The Horizon Arco 2 features an improved start up time and purer flavor while maintaining the long lasting lifespan The Horizon Arco 2 now features a upgraded triple layer liquid guiding system. The Horizon Arco 2 comes with a new T6 coil, which is a 0.2 ohm parallel coil rated for 40 to 80W and uses cotton and flax paper between the coil and the cotton to create incredible flavor. Flax paper can hold more e-Liquid than cotton and sends it straight to the coil improving flavor and most importantly of all, your overall vaping experience. Flax paper will also reduce the frequency of dry and burnt hits due to the higher burning point as well. These atomizer heads will also gradually improve in flavor after frequently being exposed to e-Liquid and heat. The Horizon Arco 2 is a 5.0ml e-Liquid capacity tank with a convenient threaded f top fill design that features dual fill holes. The Arco 2 features a beautiful vacuum plated glass tank and a stainless steel construction. The Arco 2 features dual airflow slots that may be adjusted down to your personal preferences.
