Warning plate

The sign corresponds to the product description.
It is printed on both sides equal. As a result, it could be mounted both from the outside on a smooth surface, as well as to a window from the inside. The second option is likely to be the more meaningful and more often selected because the sign is protected against environmental influences.
The print quality is powerful in order that color. The adhesive holds securely. Whether a wrongdoer can be influenced by such a shield in his intentions, I do not judge.
