Not to go into too long of a story but just moved this week and found a stack of 10 innokin prism t20 coils. I remember there was an order mix up and I ended up with this a couple of years back. I do not own an innokin endura set up. If anyone has one laying around and wants coils or doesn't use the tank , I could use the coils for my nic salts on a mod. I have the older T20 coils not the newer T20-S
