The Mig Vapor Keymaker replacement coils are made specifically for the Mig Vapor Key Maker Wax Vape Pen and the Keymaker Black Wax Vape Pen. The coils come in two different styles; ceramic and quartz. The coils are either a new ceramic heating plate coil for wax and other concentrates or a new quartz coil for wax and other concentrates. The coils use True Convection Technology™, so they do not use any combustion to heat the coils and are also temperature steady.
