In so many comments I read often that the installation of street numbers is abysmal. I have to disagree clearly. We have an old, uneven brick wall and the installation of street numbers has still worked like a charm. A bit of craftsmanship belongs might do so, but if you're not hiring too stupid to all the works actually quite good :) The workmanship is good. Unlike others, we did not have sharp edges or muddy processed at the numbers. We ordered the "6" and the "a".
