The popular manufacturer of unicorn bottles is Chubby Gorilla.
A unicorn bottle is the best tool when it comes to vaping as using such bottles means that there is no need to carry a huge e-liquid bottle wherever you go.
So, whenever you wish to move a huge amount of e-liquid from containers, consider clear bottles from chubby Gorilla.
This is indeed a quick and easy technique.
Suppose you have a clear bottle, take out the eyedropper by holding the bottle upwards.
Consider the Chubby Gorilla clear bottle and squeeze it to remove maximum air.
