Designed for children ages 5-12, The set of NatureROCKS School Age Stepping Boulders contains two small boulders, as well as a large one. These simple but highly decorative playground structures are made using high quality glass fiber reinforced concrete, which makes them as hard and durable as they look. The surface of these rocks is carefully hand painted and has a coarse texture, making them almost indistinguishable from real boulders, even up close. If the three boulders in the set are placed together they make great places for kids to sit and converse with each other. Or if a kid is feeling a little bolder, they can try hopping from one to the next, which is made more challenging by the inclusion of the larger rock. Alternatively, they can be placed separately to add onto the trails of other stepping stones, or to add to the visual appeal of larger NatureROCKS boulders.
