The Horizon Arco Sub-Ohm Tank features the brand new and very unique cotton and flax paper liquid guiding system. The Horizon Arco atomizer heads utilizes a special combination of cotton and flax paper 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 is a 5.0ml e-Liquid tank with a rotating top fill design that features dual fill holes. The Arco features a beautiful vacuum plated glass tank and a stainless steel construction. The Arco features triple airflow slots that may be adjusted down to your personal preferences.
