The 2181-2N writing sand tray is a developmental tool designed to help children build pre-writing skills and recognize letters and numbers through sensory play. This set includes a wooden tray filled with yellow sand, allowing you to practice forming characters with the provided wooden stylus. To make learning more interactive, the kit comes with colored wooden cubes featuring letters and educational cards that pair numbers with their written words. Maintaining the surface is simple thanks to the white plastic smoother, which clears the sand for a fresh start. Weighing 540 grams, the combination of wood and plastic materials makes the set sturdy enough for daily educational activities, providing a tactile experience that supports early literacy and fine motor coordination.
