      I have been using the aluminum foil type pouch the packs came in, and have been keeping that inside a zip lock bag for a bit extra. So far they seem to be staying fresh.

I followed the instructions to dry out the dessicant plug at 350 degrees in the oven but now when I look into the end of the plug I see what appears to be a solid metallic surface. I thought I glanced into the end before heating it and the surface appeared to be perforated with tiny holes to absorb the moisture. I am wondering if I ruined it when heating it or is this solid metallic surface that I am seeing normal??? Any advice on this subject will be appreciated. I also thought at one time someone else besides SBIG made a plug to fit this (if I have to buy a replacement) but I can't seem to find any other options now. Any suggestions? Thanks.
