Fun, Fun and more Fun! Place these small 3/4″ diameter clear balls everywhere around your party venue. On the lawn, in the garden, hanging from trees, shrubs and ceilings. Their water resistant design allows for use in water features where they will float. Each one has a tiny glowing white LED that fades on and off slowly. Collectively, they produce a moving firefly or fairy light effect that is absolutely unique. You can replace the batteries also. Wire hooks or fishing line can be attached using the small recessed hook. Great as a floral or table centerpiece enhancement. Also a unique Christmas Tree ornament. 2 x CR-1220 batteries included and are replaceable.
Choking Hazard. Keep away from small children. Careful placement in foot traffic areas should be considered to prevent tripping.
