Inspired by the philosophy of Waldorf education and modelled on the naturally smooth shape of river stones, these unusual building “blocks” will engage preschoolers both visually and mentally. The simplicity of the shapes leaves plenty of room for independent play and imagination. They’re perfect for balance and stacking games, embellishing playscapes, or building small rock forts. This four-piece set is painted in gorgeous fire-inspired graduated red and orange hues and looks beautiful stacked up on a shelf when not in use. The pieces are hand-crafted in Europe using lime wood and finished with completely non-toxic water-based paints and plant-based oils.
