Jacobi Jayne - Window Alert Butterfly, 4pcs

It's a distressing reality that hundreds of thousands of birds are killed every year by flying into windows. Fortunately, there's an ingenious solution to this alarmingly widespread problem. WindowAlert is a decorative decal that clings by natural static attraction to any glass surface. It reflects the ultraviolet light we can't see, creating a brightly glowing warning that's clearly visible to birds. No adhesive or special fixing is required. Each pack contains four decals.
