Well. These are actually 16 ounce bottles that have plastic caps, still have the original sealed plastic on the cap and are still wrapped in the original bubble wrap (though the bubble wrap clearly indicates that Iodine
has sublimed because they are brown).
These aren't the small bottles with the pipettes. That's why I was asking. I remember having the same problem with the dropper back in the day.
I've had these sealed bottles since 2008.
