We're coming up on the holiday season soon, and many people mail treats to family and friends. One of the best ways to keep cookies fresh (and non-crumbled) is to mail them in an empty Pringles can:
If you are going to be mailing cookies for gifts, empty Pringles cans are just the right size for holding them. Plus, the top keeps cookies fresh. Just put a length or two of strapping tape over the lid to keep it secure during mailing.
This is especially useful if you are mailing your cookies overseas, I might add.
