A pack of 5 Ego-t Coil Units, suitable for use with Litejoy top loading coil clearomisers.To replace the clearomiser coil unit:1.Keep the Clearomiser upright. 2. Unscrew the black mouth piece. 3. Hold the central rubber coated part of the tank, gently unscrew it anti-clockwise and remove it completely. 4. Holding the new coil by the bottom of rubber coated end, push the wicks (strings) down and carefully feed them into the sides of the tank. 5. Push the coil down into the tank so it comes into contact with the central metal piece in the tank and screw the coil clockwise into place, ensuring that it is screwed in tightly as the ego will not work if it is loose (do not overtighten as this may make it difficult to remove). 6. Replace the mouthpiece and attach the clearomiser to the battery.The full ego electronic cigarette kit and ego accessories are available separately in the ego range.What else do I need: These coils are compatible with Litejoy ego-t clearomisers, please note they may not be compatible with other brands of ego-t.
