General Information
Is your product made in the USA?
Yes. 100% Produced in the USA, right in our home state of Tennessee. We also buy all of our supplies and ingredients from USA-Based manufacturers and suppliers to insure you are getting a product of superior quality. From bottles to labels & ingredients, we believe that quality comes first, and there is no quality like that found right here in America.
What is vapor, and how is it produced?
Vapor is produced when a heating coil inside of an atomizer, cartomizer, clearomizer, or tank is heated by a high drain, approved lithium-ion Battery causing our E-Liquid to produce vapor. The E-Liquid is usually absorbed into a wick, whether it be a cotton wick or a silica wick. This wick absorbs the E-Liquid and carries it to the heating coil for vaporizing. That's where we come in, you use our E-Liquids to fill/refill your equipment.

What is the difference between "USP Grade" and "USP Certified" when it comes to Vegetable Glycerin and Propylene Glycol?
USP Certified means that the product maintained it's purity through the chain of custody. USP Grade means that while the product may have started out in a USP Facility, it passed through hands and was re-bottled/ re-packaged / re-distributed by vendors who are un-certified, and as such the product can no longer be USP Certified.

Mountain Oak Vapors uses only USP CERTIFIED Vegetable Glycerin and USP Certified Propylene Glycol.
Okay, I bought the stuff. How do I use it?
All of our bottles of E-Liquid are sold with dropper assemblies included! Filling/refilling can be a fairly easy process depending on your device. Generally speaking you can use the supplied dropper to slowly drop the liquid into your cartomizer / atomizer / clearomizer or tank. Remember to take it slow, and do not drip down the middle! In traditional e-cigarette cartridges, the hole in the center is meant as an airflow passageway and is not meant for dripping directly into. This can cause flooding, clogging and leakage from your cartridge/tank. Instead, the liquid should be dropped slowly into the wick inside the cartomizer / clearomizer / atomizer / tank. Slowly rotate as you drop to make sure the liquid is applied equally throughout the wick.
