Nanoblock @ Otaku House
The Nanoblock is the smallest brick in the world! Developed by Kawada Japan and are inspired by Lego bricks, the Nanoblock has the smallest brick size of 4mm × 4mm × 5mm.
The underside of the bricks are different from Lego bricks because they use a dividing flange, known as the double-ridged backing system, instead of the tube system that Lego employs.
These are official Nanoblock from Japan.
