These five adorable little wooden bowls are a must-have for every child's toy box. They can be nested together, stacked in a variety of ways, filled with little objects or used imaginatively as play dishes and cups... the uses are as varied as a child's imagination! Young children will explore concepts of size, comparison and sequencing, as well as exercise their fine motor skills, reasoning/problem solving, and hand-eye coordination. This durable, heirloom-quality toy is a great addition to any playroom, preschool, daycare or home. Made from European alder wood and colored with water based stains that are tested as safe/nontoxic according to stringent US and European safety standards. The height of bowls when stacked is about 8 inches. Nested together they stand at a little over 3 inches tall. Each bowl in the set is of uniform height (about 1.5 inches). The largest bowl has a 4-inch diameter; the smallest bowl measures about 1.25-inches in diameter. Crafted by hand in Europe. Also look for these Stacking/Nesting Bowls in other color palettes, including Rainbow colors with Blue on outside, Lollipop colors (pinks), Ocean Blue colors and Natural, unstained wood.
