You can try to get your hands on a G-Tank US , it uses several different size
juice tanks as well as a dripping atty. size (which I like a lot) and it uses stainless wicks . Or try to find a line / Preferably V2 , as some of the V1 versions tend to leak . There is a bit of a learning curve with these , and kinda hard to get consistent wicks (ohm rating ) . But they do work well , once you get them dialed in .
