Refilling requires some dexterity and precision in order to avoid spills and get a clean fill. First, you must disassemble the device and empty the lost mary MO5000 flavors already in the e-liquid chamber. Next, locate the fill port. Most vape tanks have designated fill ports, so simply locate the designated fill port on the tank, usually located on the side or top of the tank. Tilt the tank, fill the chamber, allowing for some space at the top for airflow, and reseal. Reassemble your vape and you’re ready for more puffing!
