The Aspire Nautilus 2S Tank is the newest version of the best-selling Nautilus line of tanks.  The Nautilus 2S features a 2.6mL tank capacity, a convenient two-step top-fill system, and the utilization of the time-proven Nautilus BVC Coil. The Nautilus 2S  is constructed of sturdy stainless steel material with a viewing window to easily monitor the juice level in the 2.6ml Pyrex glass tank.  Additionally, the Nautilus 2S features a two step secure-refill process which combines a threaded unlocking cap and push style top fill system to ensure the Nautilus 2S is child resistant. The Nautilus 2S features two drip tips; an elongated one for optimized flavor when used for MTL (mouth-to-lung) vaping or a shorter polycarbonate tip for DTL (direct-to-lung) vaping.  As with all Nautilus tanks, the Nautilus 2S features an adjustable bottom airflow control that can be used for a variety of vaping styles.
