Ich kann plissee-experte.de empfehlen, die haben auch Sonderformen und Kits zur Befestigung ohne Schrauben. Komplett dicht wirst du ein halbrundes Fenster damit aber natürlich nicht bekommen.

Alcohol works well for me too, but I don't see how getting drunk would help with the stickers?

Manufacturer, seller and buyer are in the EU, the import label wasn't even necessary...

Next time I'll do that and make sure to leave some marks.

You have to get to the point of "last remains" first. Dish soap worked just fine to remove the residue.

I didn't think of a hairdryer, but that's too many tools for such a job anyway...

The label says "importado", which means "imported". It really had no important information on it. Of course, compared to other things this is a minor nuisance at most, but I still get mad every time. They even added a second label saying that the bowl is not dishwasher safe. And my wife bought a whole set, 20 pieces, 40 labels.
