It doesn't hurt them, but my experience has been that plastic absorbs the vinegar smell, and THAT is nearly impossible to get rid of. I have some old ejuice bottles saved when I emptied them so I'd have spares, but had to throw away several that got that smell in them and I couldn't get rid of it again.
I got that kayfun done and filled it with the blueberry, but I didn't like it in the kayfun any better than the first time I tried it. When I vape it in the cartotank, I get the whole blueberry muffin taste; in the kayfun, the muffin kinda gets lost, and I just taste the blueberry. Which isn't bad of course, but it feels lacking, since the muffin is supposed to be there. Without the muffin, it's a "sharper" taste.
So, when I paid my credit card payment, I noticed that I did still have a little leeway on the card, so I went ahead and ordered 4 of the usual XL smok cartos I usually get; including shipping it was a bit under $10, so that didn't hurt the card any. Payday is a week from tomorrow and it should be a much better check than the last one, so I'll order some more then, so I don't run out this way again. Hopefully either Ikenvape or IBtanked will get the 3-ohm XL single-coils back in stock by then; hopefully Ikenvape, because I really want to try those; the IBTs are just Smoks I think.

And hot damn, I just saw on the tracking page that my cartos are in Atlanta, got into the sort center just after 7pm, so they should be here tomorrow.
