Nanoblock is a mico-sized building block system with its smallest piece being a mere 4mmX4mmX5mm and first went on sale in Japan, October 2008 by Kawada, rapidly gaining success and a huge following through the toy and gift markets. Nanoblock now enjoys large dedicated display sections in the largest chains of Japan, such as Loft and Tokyo Hands, giving them excellent market presence. The manufacturer also creates licensed products, special edition and trend response sets, while constantly adding further new items to the Nanoblock catalogue. Alongside this, competitions are regularly run for user-submitted creations under different categories.
Nanoblocks are coloured using soy ink rather than petroleum-based products, which not only gives them their amazingly vibrant colours, but is also better for the environment.
Additionally, Nanoblocks come in environmentally friendly sized packets, using the smallest size possible to contain the product. This means that when you do find a larger box of Nanos, you can be sure it's literally stuffed with tiny construction bricks!
