It's an eight-legged invasion of fun! These harmless swarms of realistic spiders come complete with tiny hidden sticky wheels for lifelike swarming action! Use them again and again- race 'em down windows or walls. Designed to run on smooth, clean surfaces. Ideal for mirrors, glazed tiles, linoleum, laminates, and other non absorbent surfaces. The sticky wheel may stain wallpaper, paint, wood, rubber, carpets, fabrics and other absorbent materials. Each Bug Wall Crawlers is packaged on a hanging card and is sold by the piece.
