Just look at this pretty little 7 Wonders box:
Of course there’s no scale in the picture, but the artwork is cut from the 7 Wonders box insert (which was so weak and wonky I didn’t feel at all bad ruining it for good), so you can guess from that. The box is a Alea Treasure Chest box (I’ve got two of those, both useless), so it’s just big enough for the wonder boards. The rulebook doesn’t fit in, but all I need is the quick rules, folded in half.
This box is much better than the original box. The game’s a filler and I wouldn’t mind carrying it with me, but my backpack has some limits to what it holds and those large boxes hog the space… With the smaller box things get much easier.
