【Sturdy Fir Wood】This sandbox is constructed from well-polished fir wood to ensure both durability and safety during playtime. The solid wood structure not only enhances resilience against the elements but also adds a touch of natural charm to outdoor play areas. 【Bottomless Box With Extra Liner】This wood sand box features a bottomless design and an extra liner. This combination allows for easy movement and better drainage, preventing water from pooling at the bottom and causing the sand to become muddy or waterlogged. The non-woven liner also provides a protective layer between the sand and the ground. 【Pack With Fun Features】The sand wall of this sand box adds more fun activities to the game and also functions as a backsplash for added protection.
