The Subtank mini is a brand new innovative tank that has an Organic Cotton Coil (OCC) with organic cotton made from Japan, making it much healthier and better for the environment. It can be compatible with the mini RAB base or it can easily be changed to an RBA clearomizer. The Subtank is smaller than the Aspire Atlantis and previous Subtank models that can fit most mods with a 22mm while still keeping E- capacity at 4.5 mL. This product is meant to have a larger heating component and a longer lifespan! Consumers will be able to enhance their vaping experience by tasting a purer flavor and improving their vapor production!
