Introducing the Uwell Nunchaku Tank with Pro-FOCS flavour testing technology and patented self-cleaning coil technology. This innovative and impressive sub ohm tank offers amazing performance and is also a sleek hand-polished piece of vaping kit with an expandable capacity. We should also give you the heads up on the Uwell Whirl (don’t try to say that under the influence!). This versatile and stylish tank delivers satisfying mouth to lung vaping but also restricted direct to lung draws. You would do well to choose Uwell!
