My preference is for the UCan e-liquid container
How to use the UCan eLiquid container?
Costly but way better than the Unicorn bottles. I don't know how many times I've spilled juice using the unicorn bottles.
I second this. Just picked up a UCan eliquid container with my last shipment of juice from Texas select Vapor. I love it. 10ml holding, just a few presses on the bottom button and you're done.
Quick and easy, not sure it's quite what OP is looking for, but at 15 bucks for being metal I found it a nice investment.
