This Framed Staple Wire is 4 ply ribbon wire sandwiched and then wrapped with 36ga (0.127mm) that normal machine can't do on the market. The outer wire is wrapped to be tightest and consistent, thus the ejuice is less likely to escape from the gaps but to be vaporized. As a result the spiltback is avoided effectively. With the Framed Staple wire, the surface area is increased, which enables better flavor and huger vapor production as well. If you are tired of the normal prebuilt wire and looking for performance coil, this is going be your best choice.
