Compact card box for Guillotine

At some point, Wizards of the Coast redesigned the box for the card game Guillotine. Where there used to be an insert that held the cards, most of the space is no taken up by a giant cardboard guillotine. There's nothing keep the two decks separated, and the box isn't even thick enough to hold them in a single stack! It's a terrible design. Mine finally tore open, so I designed this better alternative: it fits both the decks compactly. The sliding lid fits pretty snuggly, so you should be good to carry it without strapping it in or anything (which is more than I can say for the original box, which got so overstuffed it was usually spilling cards everywhere!).
