If you are interested in real quality and willing to pay a bit dearly for it, the very best metal vials I've found are from: http://www.sunshineproductsusa.com/ None of the cheapo ones I've seen at drug stores or a outdoor stores and the like even come close. If you really have money to burn, they even make some out of titanium. <img src="/images/graemlins/grin.gif" alt="" /> Excellent customer service as well.
