vape bottle drain

tool for draining one 30ml bottle of vape juice into another. May have to scale up to fit some bottles.second one is slightly bigger and a little different. number 3 is the better to use with a larger bottle neck I had. number 5 is what I'm going with as the final, works for my bottles.
