This tank is the “little brother” of the ever popular Aspire Nautilus Tank Kit in a more compact form. This version of the Aspire Nautilus has replicates the functionality and flavor of the Nautilus in a more compact 2ml form. The Nautilus Mini never fails to amaze its users with unsurpassed flavor production that caters to mouth-to-lung (MTL) vaping. It features a user replaceable Pyrex glass tank and stainless steel construction for durability. The included next generation Aspire BVC (bottom vertical coil) atomizers provide improved airflow, flavor and longevity over the original BDC variant. The atomizers can be replaced by the user with ease. The airflow is adjustable using a revolutionary design that allows you to have four different options with regards to how tight of a draw you prefer. To fill the Nautilus Mini tank you just unscrew the base and fill the tank until the liquid reaches the ‘max’ level marker.
