Pigeon pins intended to repel pigeons and other nuisance birds. It regularly happens that pigeons, among other things, soil your windowsill or gutter and other objects. Not only is this disruptive, it can also damage your property due to the salts in the feces. In addition, this can pose a danger to your health and that of your pets or livestock. With the pins you ensure that landing, sitting and nesting is made difficult.
