Hi, <br><br>I found something that works great to repackage Potable Aqua that I thought I'd share. While throwing some things out from an old toiletries kit, I found a tiny, slender glass vial used for a cologne sample. The vial is 1/4 inch in diameter (7mm), which exactly fits the diameter of one Potable Aqua tablet. The vial is 2 inches (51mm) long including the cap, which allows you to stack 12 tablets in the vial with a tiny fluff of cotton to keep the top tablet from touching the plastic cap. It is so slender that it fits pretty much anywhere in your Altoids PSK.
