Granted, we do not use the brochure holder for outdoor advertising purposes but for waterproof storage of Klolektüre, so I do not know how he survives storms, hail and vandalism. In extremely humid air after a shower (our bathroom is 1.6 square meters) and drops of water that come down the towel Get it keeps our journals and books but dry reliable. It's big enough that you can store more (magazines and paperbacks) each. When you open the stable door water, which has possibly collected in the lid runs, past and not into it. It is easy to clean and not scratched quickly. The lower floor is slanted with water drainage holes (we may never need it!) And facilitates removal. After the attachment (screws and plugs are supplied) it is down slightly from the wall, what elegant and not quite as "letterbox-like" effect. He is properly tightened, which is somewhat more complicated than mount him, but because he is also likely on the wall (not that I would think one of our guests would plug it in, but you never know ...).
