Pack of five. The Flow Pro Coil Head adopts the trending mesh-like heating element which can be seen as a finger-sized perforated metal sheet. Such coil structure with little holes evenly punched on a single sheet can provide larger contact surface than a traditional wire coil, or even larger than a mesh coil which is woven with strands of heating wires. Hence, the coil sheet can vaporize a lot more e-juice in a faster way, bringing both intensive flavor and massive cloud. We call it Multihole coil. Another great point is that it has a longer service life. And, the Flow Pro multihole coil is interchangeable with SMOK Baby Beast coil.
