Q - How to preserve soap so it lasts "forever"?

[Zany_in_CO]

I have a stash of a variety of experimental CP soaps I made when I first started soaping, 2004/2005. They are stored unwrapped in the cabinet under the guest bedroom sink. Once a year, I take them out and lather them up. They're all good. But I live in a dry climate. Not so sure how they would fare in a humid climate.

Thank you all! I think I will get some type of cardboard box, like a show box for storage!

I do not sell mine, but I have been crazy about making small loaf so I can learn new techniques and try recipes.
