The iClear 30S is a plastic clearomizer from Innokin. The top dual coil has it's wicks encased in a metal cartomizer-style tube lined with 24 holes which allows for plenty of juice-flow to saturate those wicks and provide a nice clean vape. No more drop and shatter glass. Very durable tank. FYI: Some citrus and cinnamon eliquids cannot be used in plastic tanks.
