plastic spider

Materials vary by listing and include ABS (Acrylonitrile Butadiene Styrene), general plastic, and polypropylene. Larger props may also use elastic or foam components.

Power options vary: some decorations plug into mains power (incandescent bulbs), many small figures require no batteries, and several animated or light-up props use batteries such as 2 AA, 3 LR44, or 3 AA cells.

Animated listings describe walking motion with posable legs, sound-activated or eerie sound effects, and lighted eyes. These animated pieces typically require batteries.

Installation varies by item: flat silhouettes include suction cups for hanging, clip-on spiders use metal alligator clips, many decorations are simply placed on the floor or tabletop, and larger yard pieces are intended for lawn placement or staking.
