Aspire's Nautilus X coils are designed for use with the Aspire Nautilus X vape tank and the Nautilus XS vape tank.
There are multiple versions of this coil available, to support both mouth to lung vaping and direct to lung vaping.
The Nautilus X coils feature an innovative U shaped chamber, forcing the vapour to pass the Kanthal coils twice before being inhaled, increasing airflow and flavour performance.
