A solid case with no zipper

First of all: For me, a suitcase is a commodity. He does not look nice, but was sturdy and withstand a lot of traveling.
I have used the suitcase in the meantime extensively. He brought several flights and train behind and passed the practical test. So it is very convenient for me that he is not fed inside. Only one case half is defined by a zipper compartment.
Since the case is made of plastic, he showed after the first flight quirks and welts. This does not bother me further, because as written above I am concerned the practical benefits. But I would refrain from taking the suitcases in bright colors to buy, because quite quickly Macken, grinding marks are then identified.

The locking system has convinced me. It works perfectly.

Also that the suitcase has four wheels, has proven to be extremely convenient and good. Hold out every single time. However (and I draw a star from), it has proved in practice that the rollers protrude very far and thereby may cancel at clumsy handling. Although they have an extremely solid. But here another somewhat more protected variant would be better.
