WOW INTERCHANGEABLE CONTAINERS
That's the name, actually, not that we're not excited. These WOW brand interchangeable containers are 8” tall x 4” square at the bottom. The tops are approx 6” square x 1” deep, and are made to also snap onto each other to make a 2” deep container—think sandwich size—and the bottoms will also snap together to make a16” tall container. You’ll get (5) tall containers and (5) tops. Dishwasher safe, freezer safe, and microwavable. Closures work with one side as a hinge and the other side as a snap lock. It might take a little practice, but a clever person like you won't have any trouble.
