Hey, so I bought my dad the vivi nova with the ego battery a few days ago because we are going away and I wanted him to try the whole ecig thing out. He comes back today for, the bar, and says "I lost that black tip thingy" I was furious!! We don't have enough time to order a new one and we don't have any vape stores in my area (NJ)..... Any suggestions on how to provide an alternate? Or is it okay to use it without?
