This product is an e-liquid enhancer. It was designed to make e-liquids "colder", NOT be vaped by itself.
This is a ready made mix that requires you to add a few drops to your e-liquid bottle until you reach the a grade of "cold" that you enjoy.
Shake well and try your e-liquid after every few drops to taste the "coldness" level.
