Square Lunch - Cobalt

Great lunch box, but needs 2-way zipper & wool felt insulation instead of plastic (RPET)

This is a sturdy lunch box for my 4th grader that starts with less plastic than most. But it would be dramatically better with 1) a two-way zipper and 2) wool felt insulation instead of plastic (RPET). A non-plastic lining like waxed cotton would also be great. These changes would raise the price, but for a heavy-use kids' item like this, I would happily pay it.
