Good display but poor packaging

Have 30 pieces bought these displays, which were also delivered amazingly fast.
When unpacking but then the disillusionment.
The displays have indeed a metal frame which is hooked on the back of the board.
These metal tongues have razor-sharp knew.
Now, if you stack 10 pieces superimposed scratch the metal tabs on the top board precisely on the display of the underlying underneath each. Since the wafer-thin PE bag and the protective film also uses nothing.
Had the displays would alternately stacked up and down does not happen.
Of the 30 displays now have 9 pieces deep, visible scratches in 2 pieces, the display is even jumped ...
Too bad, because otherwise the quality of the display would be absolutely sufficient ...
