It’s made out of stainless steel, making it super durable, but what’s also great about it is the high quality glass that was used in its construction. Never will you feel as though you are vaping using a cheap tank with this device. The airflow can only be described as incredible. With four options, you get to choose how much or how little airflow you want to incorporate in your vapor clouds. All you have to do is turn that dial and choose the option you want! This device is also using the Aspire BVC (Bottom Vertical Coil) atomizer technology to make vaping sessions that much better! With a 5ml ejuice capacity, it seems as though there is no ejuice that the Aspire Nautilus BVC Tank can’t transform into phenomenal tasty vapor clouds!
