Cartomizers are basically a cartridge and atomizer built into one single unit. To fill you simply drip e-Liquid into the cartridge filler until the top appears wet. Insert the mouthpiece cap and screw it onto your RN4081 electronic cigarette battery and use as normal.
Cartomizers are designed to be used and thrown away but you can usualy refill them for 2-3 days before you need to replace it. The time between refills is much longer than the typical RN4081 cartridge because it simply holds a lot more e-Liquid. These RN4081 cartomizers are compatible with NJoy NPRO and SmokingEverywhere Gold batteries.
People find the flavor and vapor that a cartomizer produces is much better than the standard atomizer/cartridge combination.
You will receive one package of five RN4081 blank cartomizers. These are black in color.
Cartomizers are intended to be filled once, used and thrown away. They are warrantied as such. If you choose to refill them multiple times they will not be warrantied beyond one fill.
These cartomizers measure around 3.5 Ohms resistance.
Excellent Cartomizer
