Regarding smell, although I don't own a Mighty or Crafty yet(still can't decide), I put all of my portables into snack sized zip-locks within their respective cases. Most fit into the wide ego type cases which I imagine the Crafty will fit into, but the vape in the zip can go right into a pocket or purse.
For the Mighty, I would use a sandwich sized zip. Anybody find a good carry case for the Mighty yet?
I was 8 or 9 when zip-locks started hitting supermarkets, but these "Baggies" from the future were more expensive, so many families like my own, didn't buy them.
Now that we've arrived in the future, they are everywhere, even those big freezer sized ones.
So many great uses, just don't use them for your meds. That's what jars are for.
