The Original Micro-Sized Building Block
Born in Japan. Loved worldwide. Built by you.
What is nanoblock?
nanoblock is the world's smallest building block, created by Kawada Co. Ltd. in Japan. Launched in 2008, the concept is brilliantly simple — the smaller the block, the better the detail.
With the tiniest piece measuring just 4mm × 4mm × 5mm, roughly one-eighth the size of a traditional block, nanoblock lets you create amazingly detailed models that fit in the palm of your hand.
Today, nanoblock is sold in over 30 countries with 300+ unique designs. Whether you are 8 or 80, nanoblock is totally addictive building block fun.
How Small?
The smallest nanoblock piece measures just 4mm × 4mm × 5mm. That is roughly the size of a grain of rice. This micro scale is what allows nanoblock to achieve incredible detail that no other building block can match.
