Erm. Gonna need more information here.
You're looking for atomizer heads (like for a Subtank, Atlantis, Nautilus, whatever)? Or are you looking for pre-built coils for like.. An RDA/RTA?
I'm gonna assume the primer, in which case we still need to know which heads specifically you're looking for. What tank are you using, if you know? If you don't know, pictures can help.
