Want that classic feel? All of our traditional e cigarettes have an automatic switch so there is no push button. Super easy to use and 4 terrific flavors to choose from with different nicotine strengths. Since 2009 Fuma has been selling our classic 2 piece design batteries and cartridges. Even with bigger and badder vaporizers coming out every day, we still continue to sell more and more of these guys. Give one a try and you'll see why.
