I am presently using cartomizers. You can take the top material off, wash it, pat it "dry", then put your juice on the inner material that covers the wick, replace the outer material, add juice and put it back in the plastic cover. Just make sure you don't let the wick get dry or it will scorch, and give that "burnt" taste. I'm going to order blank/empty cartomizers, now that I've figured out they can be cleaned and reused. Once you've cleaned your cartomizer, it's amazing how much easier it is to draw! I'm getting fantastic vapor!!!
