This is a 10ml bottle of unflavored 18mg e-Liquid. You can use it to boost lower strength flavored e-Liquids or use it to create your own e-Liquid flavors with flavorings available elsewhere. It is actually quite good just by itself!
Remember that by adding this unflavored e-Liquid to a flavored e-Liquid that you are diluting the flavor of that liquid.
Please be careful making your own e-Liquids. Factory liquids are formulated by educated chemists. We are not responsible for mis-use.
