As the new generation of tank systems, Nautilus Mini adopts the Aspire "BVC"(Botom Vertical Coil) atomizer technology to provide the lasting and pure taste from e-liquid while retaining the advantage of Nautilus Tank, such as the four-port adjustable airflow system that is friendly to adjust the draw, warmth of vapor and amount of vapor produced. The tiny size of Nautilus Mini with 2ml capacity makes it easy to carry, install and refill. Though its amount of vapor production is not as large as you desire, its wonderful taste absolutely will be appreciated and especially suitable for smokers to quit smoking.
