NOT COMPATIBLE WITH THE T18E TANK - please read below
The Innokin Endura T18 1.5 Ohm coil is a replacement for the Innokin Prism tank used in the Endura T18 Starter Kit (which is no longer available). The coils have 5 holes running from the top to the bottom of the coil. Be careful you don't have the T18E tank because some say T18, not T18E. The way to check is if the coil is shorter and has 3 holes because these T18 coils have 5 holes and they're taller.
