I live for modern design. Any toy that looks at home paired with an Eames chair, just does it for me. That's why this PlanPreschool Curvy Click Clack made my list. Made of eco friendly wood, non toxic paint, and e-free glue, Plan Toys aren't only high design toys, they are also sustainable and safe. Not to mention fun: marble tracks are fantastic for littles who love to build. Curvy traditional tracks and loops are also available, but I am clearing a space on my bookshelf to display this loop-shaped delight.
