Vapeccino Mate1 Replacement Pod Cartridge has two types that can be chosen: MTL & DL. They are featuring different resistances and different sizes of the air intake, but one battery box can identify the resistance of dual atomizers automatically. With the Gold plating GCT design, the lifespan is 1/3 longer than the general pod. This advanced Nanotech presents strong anti-oxidation and prevents e-juice‘s carbides from gluing to the coil so that it ensures the last puff pure as the first puff. The Mate1C Ceramic cartridge is healthier and also has a longer lifespan, offers the purest flavor.
