No, it isn’t supposed to fold into a plate, you aphid-faced faucet gnawers. It’s just a simple and good design that doesn’t use a whole lot of waste and manages to take one piece of cardboard and fold it into a receptacle for food. But remember, it is a receptacle for food. A receptacle that can be closed, and also, remind yourself that this is for Chinese food. The food famously that cannot be eaten in one sitting. You start eating it, realize you have gotten full, and have to put it into the fridge for leftovers. So you close it except now you cannot. Why? Because you gnawed on a faucet.

Faucet gnawer is new to me.
Thank you for the gift of education

New to me too. Try not sleeping for several days while running off of energy drinks that taste like pumpkin spice latte that you found next to a dumpster. It is amazing what the brain can do.
