This version of the Innokin Prism Coil has been designed to fit the Endura T22E and Endura T18E vape tanks only. There is another model available to fit the standard T22 and T18 Tanks. Registering at 1.5 Ohm or 2 Ohm resistance the Prism Coil is designed for low wattage mouth to lung vaping, making it a good option for new users. Like most of the Innokin Coil range - the Prism utilises the €˜no spill coil swap€™ system. Where each coil houses a 510 connector pin; so by unscrewing the base of your tank you can pull the coil straight out and replace it, quickly and cleanly. Contains: 5 x 1.5 Ohm Prism Coils
