Texo is the award-winning 3 dimensional design and construction system by architect, author and designer Lester Walker. The beauty of Texo is the variety of building systems found within one toy: simple puzzles, shape sorting and color matching at its most basic level, the system allows for a gradual progression to stacking the interconnected shapes and on to advanced architectural models such as bridges, houses, skyscrapers and more! Solid wood planks coupled with the geometric precision of molded plastic connectors and rods enhance the design and construction potential. Also included is a deluxe Activity Guide with how-to's, commentary and step-by-step instructions on maximizing the potential of Texo. Ages 3 .
