Nano building system
Appearance
On August 25, 2004, Mega Bloks released the Nano Building System. These blocks were the world's smallest building block to date and allowed the builder to build more detailed cars, trucks, planes, or whatever they wanted. Nano Building System was released in all major retailors as well as online retailors. The toy line lasted for a year and a half when it was discontinued in 2005 due to low sales.
