Have all the covers thrown in the trash

The covers look tidy. At the processing is initially nothing to complain about. But in everyday use as a sofa pillow cases these have not proven Kissenhüllen in my view.
I had to realize that they give off a shiny dust that has spread especially on the sofa and the table. Washing has not helped. Since the cases are made of plastic and I did not inhale the small Kunststoffstaubteilchen, I have disposed of the cushion covers in the garbage. Too bad about the money. If you stand around the pillows only as an ornament, you do not have the problem safely.
