## Long description

Polesie Sand Mill Set No. 557 with Sieve Base — Fortress Large (model 57266) is a children's sand and water play set designed for building, pouring and sifting activities in sandboxes and at the beach. The set combines a rotating mill mechanism with a stable sieve base, allowing children to experiment with sand flow, water movement and simple construction while developing fine motor skills and hand‑eye coordination.
Advantages
The set provides an integrated sand mill and sieve base that supports both dry and wet play. Its design enables continuous pouring and cascading effects as sand or water passes through the mill, promoting prolonged, focused play. Components are lightweight for easy handling by children and the open structure is easy to clean after use.
Suitable for
 Sandboxes and beach play where pouring, sifting and water flow are central activities
 Outdoor preschool and kindergarten play sessions focused on sensory development
 Home use for supervised water and sand play on balconies, patios or indoor sensory trays
 Role‑play and creative construction games that involve building small sand structures and fortifications
When it may not be suitable
The set is designed for young children and is not intended for use as a climbing or supporting structure. Very small children should be supervised during play with loose sand or water to prevent ingestion or inhalation of fine particles. The product may not be suitable where heavy-duty or permanent outdoor installation is required.
Key specifications
 Type of play: sand and water mill with sieve base
 Primary materials: lightweight, child‑safe plastic
 Intended use: manual pouring, sifting and water flow play
 Age group: suitable for preschool and early primary aged children (check local recommendations for small parts)

How to use
Place the sieve base on a stable, flat area in a sandbox or on the beach. Position the sand mill on the base and fill the top funnel with dry sand or pour water to set the mill in motion. Encourage children to experiment with pouring rates and amounts to observe how the mill rotates and how sand or water passes through the sieve. After use, rinse components with fresh water and allow to dry before storage.
What to consider before purchase
 Supervision: adult supervision is recommended for younger children during sand or water play
 Compatibility: ensure the set fits your sandbox or play area dimensions
 Cleaning: consider ease of rinsing and drying if used with saltwater or wet sand
 Storage: check available storage space for lightweight plastic components
Usage recommendations
Use the set with a mix of dry sand for sifting demonstrations and small amounts of water for continuous rotation; alternate dry and wet play and rinse after wet sessions to prolong component life. Encourage constructive play by combining pouring with small building tasks, such as creating ramped channels that feed the mill.
