This is the 2nd version of Chubby Gorilla Eliquid Bottle with Hat Dropper. Advantage: -The Hat-Dropper is easier for end-users to take out the dropper from the bottle. -The Hat-Dropper can be closed to the bottle tightly, it will not happen that the eliquid get inside beween dropper and bottle, then dropper get slippy to fly off the bottle when end-users squeeze the bottle.
