"The primary consideration for using vials with teflon lined caps is the caustic nature of potable aqua. Nasty stuff."

Understood. I was initially looking for teflon coated. However, not being able to find them at what I considered a reasonable cost (including shipping charges), I gave up and decided I didn't really need repackaged H20 tablets in my pocket kit. Instead I now throw the entire (unopened) original bottle of tablets in my larger kit (Nalgene bottle based) that sits inside my daypack. My daypack is with me 99% of the time I'm outdoors, and for that 1% of the time when I might have only my pocket kit I'll just have to resort to boiling.

And those cute little non-teflon bottles I bought? I guess I could try making cap inserts out of teflon plumber's tape. Or I'll find something else to do with them. Right now they're mostly just sitting there lined up on a table so I can periodically walk by and admire their cuteness! <img src="/images/graemlins/smile.gif" alt="" />
