These are all the tanks with pre made factory coils available.
Some of these are MTL and most DL
MTL= Mouth to lung (imitates a cigarette drag) inhale into your mouth before you take it into your lungs
DL= Direct Lung ( Directly inhale vapor into your lungs)
Direct lung tanks use more E-Liquids, they however produce more vapor and better flavor (please note all tanks are to be considered DL unless stated otherwise)
