Cool box with quirks

Open the box really happy with the work. Since it is possible to transport various types of food in a box.
If you like Soduko solves - has certainly fun when filling the compartments. Because what could be best where fit into it?
Even if you have filled it yourself, it's a little bit like a surprise when you open a trade after another ;-)

Now the hook:
You have to take the box apart completely to get the thing clean. After a short time already broke the first flap away. The hinges make it also determines much longer.
The subject is quite low down and to get ran only when the upper compartment has been completely folded, so that everything ends up in the lid.
The box is not tight.
