Simple to construct (no special tools required), and easy to maintain! The eco-friendly timber is made of recycled plastics and sustainable hardwood fibers. When your child outgrows the sandbox, repurpose it as a raised garden bed, landscape edging, tree ring, or integrate with other Series Two Frame It All components.
