I ordered some of these. They haven't arrived yet, but do you use them just as is or do you add a drip tip and sleeve over them? Or do you just screw on and draw. 
If they have holes punched in them they are intended to be used in a tank. There are various techniques for priming the carto and filling the tank. Youtube is your best friend for learning how to do this.


Simple!
Wrap the holes up with electrical tape and use it like a normal cartomizer. I do it all the time with punched cartos when I decide I don't like the juice enough to keep a tank filled.

If you don't have a tank, just cover the holes with electrical tape (not a lot, one "around" will do). Then drip 40+/- drops, and you're good to go! All you'll have to do is top off the carto every once in a while.
EDIT: You can't tell from the first photo because my phone camera sucks, but it IS a flanged carto. To be exact, it is a single-hole, single-coil 2.0 ohm Smoktech XL replacement cartomizer. Whew, a mouth full!
