I am for but it might be too costly to stock two different boxes of eack size.

At our local pizza shop the staff write on the box with a marker saying what pizza is inside to avoid this issue. Ask them to do it for you.

If you are getting 5 boxes there must be more than one person eating. It occured to me that all the boxes would need to be opened anyway. You are performing a service for your fellow pizza eaters. Good show, keep up the good work.

GREAT IDEA!!! submit it to all your local pizza places. Maybe have the boxes display what kind of pizza it is, and if its a specialty order, it would be one kind of box labeled specialty.

Good idea - but not happening because it's too expensive. Usually there's a sticker on the side of the box that says what kind it is, though.

i have another related idea about Pizza boxes. If you see generally pizza boxes are very large and it is very difficult to carray them along while you are walking or cycling or in bus or some place where you there is not enough space available to rest your pizza upon. Since you generally cut a pizza in 8 wedge. Pizza box should be a wedge shaped box with eight containers holding each pizza piece. You should be able to take out a single piece without opening the other ones. This way you can comfortably carry your pizza along and you dont have to sit at a proper place to eat it. just take out one wedge piece and have it.

Good idea, but impractical as they would need too many different types of boxes cluttering up the kitchen. And some places do 15+ types of Pizza.
Better to write on the box as sugested previously. My local chinese does this, CFR, SSC etc. But I think this is mostly for their benefit so they can check the order as it goes out the door.

It'll cost them more to manufacture the coloured pizza boxes. Guess who has to pay for that. A much simpler solution would be to start using those goddamn check-boxes! Seriously. I've never seen anyone tick them
