Because CitiBlocs are manufactured in Vietnam, the pieces are not only high quality but are also affordable and so easy to use. Best of all, the precision cut blocks of wood are green, crafted from New Zealand pine. The beautifully simplistic blocks, designed for ages 3 and up, are ideal for solo play or a family fun session with grandparents and siblings. Through play with the blocks, grownups can introduce kids to architecture and design, history, mathematics and science with success guaranteed and memorable results. There are seven available building sets — from the starter box to the ultimate experience. CitiBlocs has received the following honors: 2009 Tillywig Top Fun Award, Creative Child Preferred Choice Award, Mr. Dad Seal of Approval, Dr. Toy Best Vacation Product for Summer Award; Dr. Toy Best Green Product Award and Best Products Award 2009, iParenting Media 2009 Outstanding Products; National Parenting Center Fall 2009 Seal of Approval; 2009 Parents' Choice Approved Award; Oppenheim Toy Portfolio Gold Seal Award; and What the Stuff Toy Review - Four Star Certified Seal.
