WA4 Window Alert Decals
Millions of birds are killed or injured each year by flying into windows. Alert birds to this danger with WindowAlert static cling decals. Translucent, in a maple leaf shape, these decals create a decorative frosted glass appearance to us - but to birds, who can see UV light - they are a clear warning. New technology brilliantly reflects ultraviolet light. Easy to apply, peel off to clean window and re-apply, leaves no sticky residue. Four 451 decals per package. NOTE: For use on the exterior of windows and Not for use on tinted glass or overlays.
