The ergonomic design and impressive performance of Vapor Flask have made this unique mod a favorite among vapers. Now Vapor Flask and Vapor Shark have worked together to redesign this mod from the ground up. In typical Vapor Shark fashion, new and innovative features have been added to take this dual battery mod to the next level.
