Okay, help.
How do you fill these things?
I've got both the top black cap off and inner black cap out (the one with 2 tiny holes on either side), but upon sticking a flashlight in there and seeing the inside of the cartomizer, I don't know that's it's a good idea to just start dripping liquid in there - I don't see any filling to drip onto.
I don't know what I'm looking at, to be honest. It looks like maybe the filling is blocked off by more plastic? 
If I can't drip the liquid in thru the top, can I fill them thru the bottom hole? If so, how many drops can I get in there?
