The BVC coils are an upgraded model inspired by the old Aspire Nautilus coils and feature a “Bottom Vertical Coil” instead of the previous “Bottom Dual Coil” design. The new BVC coils only use a single coil and are designed to last longer than the old Nautilus coils. The Aspire BVC coils are compatible with both the original Aspire Nautilus and the Nautilus Mini. These coils are available in 1.6 ohm. Sold in 5 packs.
