I need a box to let interject Bestellzettel A5. But the case is perfect, especially since he is exactly cuboid and therefore stands by itself. It is processed stable and clean, even the lock closes properly. The fact that he is made of steel, has the additional advantage that magnetic Extras (advertising magnets, pen holder) can be attached.
A friendly teacher ordered the same case now for his class, so there Grump list can be inserted.
