On their search, type in eliquid, comes back with a metal canister to decant eliquid into.
Type e-liquid, several hundred products come up. But wait, I want 30 ml bottles. Forget it, never could get to it with search. That's right, scrolled through hundreds of products to find what I needed.
Oh, Eric, I know you will appreciate the irony here. I'm opening up my blue evod [not your baby blue, the dark blue] and I'm all WTH? There's a protective cover over the tip! ROFL, then I take the bottom off to compare the coils to my really expensive genuine Evod, the base unscrewed and the coil stayed in the tank!! But wait, there's more! [How can this be, you ask? Because I am involved. None of this crazy stuff happens to you guys!!] The coil stem is long, way longer than the comparison pics I've seen in this thread. This joker has a T3 stem over that coil, that unscrews from the base like an Evod. They have the T3S here for goodness' sake!! Still the tank and mouthpiece of the Evod. We have to rename them Evod3S, huh.
I now want some of those T4's you are talking about, just to see what the stems look like. Bet they're short like Evods.
Aha, the mystery is solved. They now sell heating core long and heating core short. Cool!
