The EASY FILL oil cartridge makes filling your cartridge very simple. Just unscrew the top of the cartridge and the top along with the entire center pole will be removed. Using a syringe or dropper, fill the cartridge with your product up to or just right below the 0.5ml fill line. Then reassemble the cartridge by screwing the top and center pole piece back onto the cartridge.
Tip: it helps to jiggle the top portion a little when reassembling to make sure no air bubbles are trapped beneath the center pole.
