I placed an order last month that included the 510 clear colossal dual coil cartomizers. I ordered these in 1.5 and 2.5 ohms. They all came unlabeled in the same package, and I have no idea which are which. I emailed them through their "Contact Us" page, but have heard nothing from them. This was at least 2 weeks ago, possibly 3.
I'm posting this hoping that they will respond, since they don't through their own website.
