Fits nicely in your hand

Posted on 05/08/2016 There are tons of things to love about this mod that was built with the serious vaper in mind, but my fave is how it feels in your hands. Pens don't give me the huge clouds I'm looking for, but I also felt self-conscious about walking around sucking on a huge boxy model. With this I get the best of both worlds.
