EC/M Series Coil 1.0 Ohm: • Fuller and more authentic flavour. • Evenly and cleanly atomises the e-liquid for a better vaping experience • 1.0 Ohm: suitable for MTL, recommended for 40-50VG ratio e-liquids. For best experience, we recommend replacing the coil after every 3-5 full cartridge refills, or when changing flavours. Package comes with two (2) coils. For use on AirsPops Pro only.
