When we first saw these we just couldn't wait to play with them! Natural unit blocks are made from reclaimed cherry, apple and elder trees. They are sanded and oiled for playability and long-lasting durability. This 36 piece set contains blocks (from 1" to 10" long with diameters from 2" to 7") similar in shape to those pictured. Blocks come in a cotton twill drawstring sack for easy storage. Hours of creative building!

Unit blocks are precision-cut in 2 centimeter increments for logical building.
