See what Chris Byrne - The Toy Guy - has to say about Citiblocs! http://www.timetoplaymag.com/
Building with Citiblocs is all about making connections and learning naturally. With Citiblocs children can create fantastic worlds from their imaginations or from the environment that surrounds them. They can discover the principles of math and science that allows bridges to span great distances and super-towers to reach the sky.
