When the time comes to keep track of inventory, the Cambro 6 qt CamSquare® Food Storage Container (6SFSP148) really comes in handy. Graduations are marked on the outside of the clear surface to make it easier to keep track of what you have and what you need. Made of polycarbonate, this container is just about unbreakable. It works well in freezers or in the pantry, depending on what you need. If you’re short on space, easily stack Cambro square containers on top of one another to make the most of your shelf space.
