This 3D bat decoration set creates a haunting Halloween atmosphere with 36 realistically shaped bats featuring adjustable wing angles for lifelike positioning. The included LED lights - with alternating red, purple, and blue flashes - attach easily to each bat, producing an eerie glowing effect that enhances both daytime and nighttime displays. Complete with 70 adhesive squares, the set allows flexible placement on windows, walls, ceilings, or outdoor surfaces while maintaining secure attachment throughout the season. The durable PVC construction withstands repeated use while remaining lightweight enough for various hanging applications. The pre-cut folding lines enable customized wing positions, creating dynamic flying formations that add depth to haunted house scenes. The removable adhesive ensures damage-free removal after Halloween while preserving the bats for storage and future use.
