I'm perplexed now, the plastic tubes are cut a bit short, but when putting the outer sleeve on they're going all the way down to meet the rim on the bottom of the cartomizer, I'm assuming the sleeve is designed to attach to the top of the plastic tube, I've checked the plugs, they're in all the way, there just isn't any click to hold them on?
So far I have 4 like this, I have 4 more packages to check, will try to update you today, thanks!
