Rock on, all you gardeners! Here's a charming border accent for your flower bed, or as a marker for your driveway or sidewalk. Eleven faux rocks glow softly with LED light after a charge from a full day of sun, lighting the way for 6-8 hours. Coming in gray and rusty shades, they have slightly different sizes and shapes to imitate reality. Solar panel uses one AA Ni-CD battery (included). String of lighted rocks is 20' 6". Rocks are 2-5 1/4" l x 1 1/2-3" w x 2-3 1/4".
