You can stash a house key underneath this petite artificial rock from Outdoor Essentials®. It’s strong, hollow, and looks just like a real stone. The 3-pound rock is easy to move around. You can drill holes in it to run wires or a hose. Available in tan or gray. Colors will vary from the pictures because each rock is hand painted in blended colors for a natural look. SIZE NOTE: Interior dimensions are not uniform. The interior shape matches the exterior shape, so the height and width will not be the same across the entire rock. The size given is the overall dimension. 5-year limited warranty.
