Thanks for your reply. They're in a storage box with a few other things to keep them away from dust/dirt. They're between a glassine sleeve at the moment, which is also inside a regular envelope (for a bit of added protection) and I put the envelope inside a regular plastic zip-lock bag.

The archival box sound great and I will probably buy one if that's the best container to keep them in.
