My neighbor once ordered one of those free trial e-cigs (before I found ECF) and by the time he got them to stop charging his credit card he had like 6 boxes of prefilled carts. I got him set up with a 510 kit after someone stole the batt and atty that go to the carts. He doesn't want them to go to waste. I thought if I could find out what size atty will fit these carts I could get him an adapter and atty to work on the 510 batts he has. The boxes of carts say CigeleX and they *look like they go over the atty the way a 306 does, but they are skinnier. Anyone know what atty these go to? TIA
