A set of 12 self-adhesive 3D bat night lights (variant: Bat-12PCS-1Box) for decorating walls, doors, and windows at Halloween. Each bat is made of PVC and lights up in purple and green from a built-in LED powered by a button battery, which is included. Light self-assembly is required before mounting. Packed dimensions are 190x170x110 mm (7.5 x 6.7 x 4.3 in) and the boxed set weighs 486 g. To apply, peel the backing and press the bat onto a clean, dry, smooth surface; press firmly for a few seconds so the adhesive sets. Wipe with a dry cloth only, keep away from water, and remove the batteries before storing between seasons. Screen colors may differ slightly from the actual product, and hand-measured sizes may vary slightly.
