Empty 510 Cartridges are the same 0.5ml screw-on carts we fill in-house, sold empty so you can fill them yourself with our kanna, blue lotus or kava refill liquid. Standard 510 thread, so they fit the battery we sell and any other 510 battery.

How to fill. Pull the mouthpiece, use a blunt-tip syringe to fill down the side of the tank (not the center post) to just under the top, press the mouthpiece back on, and let it sit upright for 10 to 15 minutes so the coil soaks before the first draw.
