Reusable pizza box’s

I work at a brewpub and we deliver 30 16” pizzas to the local high school 3 days a week. All told throughout the school year that’s somewhere around 3300 pies. Over 1700$ on pizza box’s. Has anyone seen any form of reusable pizza box, I’ve looked on webstaurant and other online stores and have found nothing remotely serviceable. My next thought was 3d printer, but I know as much about that as rocket science. Any ideas?
