CLOCC stands for Child Lock Organic Cotton Coil, as the CL tank is a child resistant sub-ohm tank. As the name implies these coils feature a Japanese organic cotton wick in a stainless steel housing. We carry these coils in two variants. The first is a 0.5 Ohm coils with a SS316L resistance wire. This coil is suitable for all sub-ohm mods and can also be used with devices that support SS Temp Control Modes. The second variant we offer is the 0.15 Ohm coil with a nickel (Ni200) resistance wire. The Ni200 coil can only be used on devices with support Temp Control.
