I have some liquid that has the same flavor profile as some disposable cartos I have, and I have refilled them all. You can refill them no problem at all, pretty easy. I know they are disposable, and junk, but why not, better than throwing them away after 1 use. The attys haven't burned out. Has anyone played around with "curing" them at all? Like letting air pass continually over them and concentrating and evaporating some of the moisture out of them? just thought I would ask. Thanks in advance.
