This is the award-winning, three-dimensional puzzle that challenges youngsters to think in multiple dimensions, builds spatial awareness, and develops motor skills. Winner of the 2008 International Design Excellence Award, this puzzle exists in four color-coded layers that nest inside one another. Children must turn each piece just so to fit it through the outer sphere's fixed opening, making the puzzle progressively harder as they advance from one sphere to the next. The puzzle's 21 pieces form a 3 1/4"-diameter sphere when completed. Made in Canada. Ages 5 and up. (12 oz.)
The Award Winning Nesting Spheres Puzzle comes with The Hammacher Schlemmer Lifetime Guarantee. If this product ever disappoints you, for any reason, you may return your Hammacher Schlemmer purchase for exchange, credit, or refund.
