The huge box hides smaller colorful boxes, each containing a small number of pieces. The boxes from the Genii Creation Transportation set have been serving us faithfully for a couple of years. I moved various puzzles and small building sets there. We did the same with the boxes from the Playground set. The huge box itself is unsuitable for storage, the building kit pieces fill up only a small part of it. So all Genii Creation sets was moved into a spacious plastic box.
