What can I store Iodine crystals in?

Iused to make Daguerreotypes using the Becquerrel process and I stored my Iodine in a gl vile. You will find that iodine oxidizes metals, and stains just about everything, so forget a steel box. You could place it in a small airtight plastic container but I would be sure to place it in a ziplock bag as well, and don't place it on the carpet or on clothes. I made that mistake and it turned part of my carpet reddish brown. I personally stored mine in a gl vile with a rubber stopper, but even then the fumes would leak out and and stain whatever it was next to. Seriously though a small gl vile which you can find in a chemistry supply store is the best idea.
