Just wondered how others carry their carto/tanks around. I've got 3 IB tanks, 2- 19mm and one 25mm. If I take off the drip tip they fit into the "Thingy", but I don't want to take off the drip tips. Found one perscription bottle that the 19mm with drip tip fits in but it rattles around a bit. Or do I just carry too much stuff everyday. Wait let me count. Ok got two empty so that's only 10 with juice in em. (Yea I know I carry a lot of different flavors) I'm more concerned about my new carto/tanks than the nova's and stardust's
