What a wonderful way to light up the night in the miniature garden! String the star lights up along an arbor, light up a tree, or hang them on a fairy house for special occasions. The indoor light string requires 2 AA batteries (Not included.) It includes a 6 hours ON/18 hours OFF timer feature. The string is 40" long with 20 lights (spaced about 2" apart). The lighted wire string is submersible in water, but battery pack is not waterproof so it needs to be protected.
