To use your Pure Clear Hemp vape juice simply open the E-liquid bottle. Then open your vape cartridge or open your vape pen cylinder that you are refilling. Once both are open, carefully use the pointed end of the E-liquid bottle to fill your CBD vape cartridge or your vape pen. Once it is full of E-liquid then reclose your vape cartridge or the vape pen cylinder. Then put the top back on your E-liquid bottle and store it for your next fill. Store your E-liquid at room temperature and out of direct sunlight. If you have purchased a vape pen CBD cartridge then remove the old cartridge on your vape pen. Then open your new Pure Clear Hemp vape cartridge from its blister pack and screw the new vape car on to your vape pen. Once it is screwed on properly, press the on vape button five times to start your vape or if it is a button-free vape pen, or is already started, then give it a gentle pull, and take your first hit of CBD vapor. As your pen heats up each hit will provide you with another generous amount of CBD vapor until your pen runs out.
