This environmentally friendly wooden Geometric Stacking Puzzle is made of wood from FSC-monitored sources, painted with water-based paints, packaged in a box made of recycled materials, and printed with soy-bean ink. Created with a 2-year-old in mind, this all-wood puzzle features stacking and counting elements to help kids think and learn. Each of the four puzzle pieces contains one, two, three or four posts on which children can stack a circle, rectangle, square or triangle. Each shape is made with a different number of holes so it can only be put on the correct puzzle piece. Tested to meet European and U.S. safety standards. Awards: Parent's Choice Award 2010.
