Especially if you vape wax often, having extra coils around is never a bad idea. Use the extra coils to avoid mixing different wax brands and to help maintain the purity of taste when vaping different products. The ceramic rod in these coils is an upgrade from the wick. Great vape deal for coils and a purchase to consider when ordering any micro vape pen kit.
