The newly added NotchCoiTM 0.25ohm Direct Lung head which made of stainless coil, can last longer and can be used under high wattage condition. Combine the surface area of a Clapton coil and the fast ramp up time of a traditional coil and you get the simplest, yet innovative coil design. Coming from the creative mind of Jaybo, the NotchCoil has an abundant amount of surface area for that full and saturated vapor. With the heating element constructed of stainless steel, the NotchCoils heat up in a pinch and produce a very clean flavor. Just when you thought vaping was reaching it's peak, think again.
