The Nunchaku bu Uwell is an amazing low to mid wattage sub ohm tank. 

Flavor is fantastic, vapor production is substantial, and coil life is solid. These are clapton coils, meaning there is a smaller gauge wire that is wrapped around the primary coil wire. This is done to increase flavor. 

Nunchaku coils use a nifty press fit mechanism to install, making them very consistent. 

Nunchaku coils come in packs of 4.

• A1 Claptonized 0.25ohm
  Wattage Range: 40watts – 50watts

• A1 Claptonized 0.4ohm
  Wattage Range: 45watts – 55watts
