"I'm on the lookout for another small travel size Listerene bottle."
Is that glass or plastic or what?
I have lots of ordinary white polyethylene bottles, 0.75 oz, 2 oz, 4 oz, 8 oz, etc., with hard caps and squirt caps. Then I have some clear plastic bottles that are tall cylinders with hard caps.
Then there are other bottles that are really tough. I think they held Louisiana hot sauce. Boy, you take that hot sauce along and you don't need any stove.
