Instead of tobacco, tar, and other staining properties, e-cigarettes are filled with flavored liquids. The team at Marz Vapor handcrafts all its customized "eJuices," which emit nicotine mist, rather than plumes of thick smoke. The liquids can be assembled into hundreds of tasty combinations, which visitors can sample at Marz Vapor's in-store bar. Once they settle on their favorite blend, customers can load up on the retailer's e-cig gear, such as customized vaporizers, batteries, and tanks.
