So i broke my the plastic tank today in my vivi nova. Mine has almost like a metal sleeve around it, with a slit to see the juice. My question is can I get a straight metal tube to replace it? I don't care about seeing the liquid as I'll know when to fill by when it tastes bad. I was looking at Vision Standard Vivi Nova 3.5ml Metal Tube [vis-std-vivi-nova-mtl-tank] - $1.99 : ECIGSPLUS.com, Discount Supplier for Electronic Cigarettes, E-Liquids, Supplies and More . Is this like the sleeve part or the plastic part that broke? if someone can fill me in that'd be awesome! Thanks all!
