This set of unit blocks for a child between ages 4 and five includes 8 cubes designed by Friedrich Froebel as the first building blocks to be given to a child.

These unit blocks are made in the United States from FAS quality, knot free Michigan and Indiana maple hardwood. All blocks are rounded on the long edges and sanded and softened on the ends and corners. Tolerances are within .01 inches.

Unit blocks made from forests using sustainable practices mean you can buy them with the assurance that new growth is far in excess of lumber takings, and that workers will be able to sustain themselves and their families from your purchase.

‘Going green’ often constitutes getting back to basics and surrounding one’s family with non-toxic goodness as well as visually engaging design. Eco-friendly toys are a significant household investment, particularly when the product is as timeless as these blocks with quality craftsmanship through and through. It is great to know that interactive design like this still comes in the form of beautiful objects, for both budding green minds and a lifetime of play.
