IMPORTANT INFORMATION:

These coils fit both the Modvapa Sub2 Mk.I and the Modvapa Sub2 Mk. II.

ModVapa replacement coils do not have the metal casing found on most other replacement atomizer heads.  The coils screw into the reusable casing that ships with the Sub2 tank.  Please be sure to separate used coils from the reusable casing to dispose of them; NEVER THROW AWAY THE REUSABLE CASING THAT COMES WITH YOUR MODVAPA TANK!
