Made of stainless steel, the new NotchCoil DL (direct to Lung) Head from Joyetech lasts longer and has the capacity to withstand higher wattages than previous coils produced from Joyetech. This pairs perfectly with the Cuboid Mini or Cubis Tank and supports 4 different modes: VW, Temp SS316, Bypass, and TCR modes. All of these features, combined with its improved resistance & ohm accuracy, bottom feeding system, and increased surface area create a vaping experience like never before.
