All four cases have the same orange-colored plastic shell dies, there is unfortunately no distinctions of the inserts in the four suitcases. Who wants to accommodate larger parts, fails. In addition, the case caught all in their guide rails, but especially the lowest, which is to figure out only with great force. Anyone who wants to store many of the same things and the distributor not often needed, may have something to cope. Who wants putting away many different things in different sizes and the carrier still needs to frequently, is definitely wrong hands here. Negative is also that the stakes are simply deburred deficient, there is here to make matters worse, even the risk of being cut in the fingers or hand.
