What is e best way to carry extra filled ce2s? I usually take my 2 batteries and put a ce2 on each then fill a couple extra and take those along with me so I don't have to drag a needle and juice bottles around with me. My problem is they leak so bad that half the juice is gone before I can use it. I wrap them with paper towel and then stick then in my empty green smoke cart pkg (waste not want not) then I put them in a zipper part in my purse. Does anyone know if they make any kind of end cap for these like they have with the tanks? Gee there is a money making idea for someone. Hopefully once I get my fluxomizers I won't have as much trouble, but that won't be for awhile. In the mean time any suggestions? Thanks
