The Wire Doctor competition wire.  Stainless steel, low resistance wire.  

This high-performance stainless wire is great for those of you who enjoy your low-ohm builds.  In order to achieve a safe resistance, it is very highly recommended to do at least 3 more wraps than usual and make sure you use a 3.5mm-4mm drill bit or coil jig.  These wires' lower resistance allows you to build bigger coils for more surface area.  This increases flavour intensity and vapour production without sacrificing performance.

Please take some time to understand ohms law and battery safety.
