Kanger Protank clearomizer is the first glass clearomizer. Protank's tank is made with glass material and compatible with various ejuice, which makes your vapor more healthy.
Protank has the same bottom coil heating system, same ego threading as EVOD clearomizer. besides, Protank's bottom coil head and metal base is also detachable like EVOD clearomizer, so it will be less expensive to replace a coil.
When the coil head dies, you can keep the metal base and replace only the mini coil head.
Each protank clearomizer can hold 2.4ml ejuice.
