I received a set of Nano Blocks while I was at Toy Fair. Ohio Art is the U.S. distributor for them. These things are very, very tiny but fit together pretty well. You can make a bunch of different models with them. While they are cute and interesting I’m not a big fan of their price. The little tree frog that I got goes for $10.99. It may be complex to make these pieces but not worth that much in the least. You can spend that same amount on Mega Bloks or LEGO and get a toy that you can actually play with.
