Ok sorry but I still consider a vivi nova a clearomizer. Whatever. I saw one the other day that was metal but had a sleeve that was clear to see the juice level. I've seen the slip on sleeves but this one looked like a complete cover/tank whatever you want to call it. Suppose to resist the naughty juice that eats up tanks. Can't remember the right words but the members will know what I'm talking about. If it resist the juice I want one really bad. Didn't get a chance to talk to the person but it would look great on my Provari, SB. Black, with shiney caps like the provari oh yea baby. ANYONE heard of em? or seen em.
