These do NOT fit the Nautilus or Nautilus Mini.
These are the NEW Organic Cotton Bottom Vertical Coils - The Aspire BVC are Bottom Vertical Single Coils while the original Aspire BDC Coils are Bottom Dual Coil.
These new Aspire Cotton coils should be allowed to "rest" after filling for a few minutes, to allow them to absorb the liquid. The cotton material should not be allowed to dry, so make sure to refill before running empty.
These coils fit the ET-S, Nova, CE5 and all other Aspire units except the Nautilus which takes a much larger coil. Featuring dual heating coils to provide twice the vapor while also taking advantage of a bottom feed design so that the coils are always being fed just enough juice. NO exposed wicks, the liquid goes into the four holes on the side of the coil. This is the version with 4 holes, it is the new one.
The Bottom Vertical Coil (BVC) design is a major upgrade when compared to similar single coil tanks because of the uniquely designed replaceable coil and airflow system. It was designed differently to eliminate common issues such as an airy draw, gurgling, and leaking that users often experience with other clearomizers. It also works to eliminate outside influences on flavor to provide a true and pure taste
