The Nautilus Mini is a mouth to lung style tank and is often considered as the best tank for beginner or moderate use as well as those who like a mouth to lung vape. Paired up with a shield, this is by far one of the most durable tanks to date. We recommend cleaning the tank every time you change the coil. To clean the tank; disassemble, rinse pieces off with warm water, dry with paper towel, and then reassemble.
