The caps have been made to fit the Tobh Atomizer, Cartel Stillare, Halo Cap by Capitall, and Vulcan RBA, Plumeveil, Patriot v2. (Tops may fit other atomizer sleeves, however, we specifically design our caps for these RDAs) Each top will come with two sets of O-Rings. 1 set of o-rings will be made to be used with the Tobh and Vulcan RBA and the other set will work with the Stillare and Halo Cap. There are two styles of caps in two different colors. One style mocks the tobh cap and the other style mocks the cartel cap.
