The 7's Cobalt Blue Glass Mixing bottles come in a variety of sizes and two cap styles. Currently we offer 15mL - .5 oz., 30mL - 1 oz., and 60mL - 2 oz. bottles with standard caps or dropper caps. These bottles make it extremely convenient to store your liquid for longer periods of time and give you the ability to mix your flavors! It is also now possible to mix your e-liquid strengths between high and non-nicotine levels.

This tinted glass bottle with dropper preserves your nicotine solution and makes it easy to refill your cartridge. Most companies use the cheap plastic ones but these are much better. I noticed the nicotine on the plastic ones eventually ate away at the plastic on the bottle, I'm guessing that can't be good for you. I will defiantly stick with these glass bottles.

You can tell the quality of this glass bottle because of the dark tint it has to preserve the integrity of the flavor solution, and it comes with a dropper makes refilling your cartridge easy. The dropper is even glass and not plastic like the cheapo brands I spent the same amount of money on.
