Simply fill the box with any canned goods that have been taking up space in your pantry. If you have multiple boxes, you can use each one for different categories of items.
You can even make items easier to find and make your pantry look nicer by wrapping the box in decorative paper and making a paper label to attach to the front.
Try to keep the back of the box open so you can easily move items in and out of it. The boxes’ square shape makes them very efficient for food storage of all kinds.
