Do your kids still play with blocks? Mine (ages 5 1/2 and 8 1/2) still do (though the older one won’t always admit to it). As NYC kids, I think they’d adore this New York City in a Bag block set by MUJI. Each set contains 8 wooden city structures (including landmarks like the Empire State Building, Guggenheim Museum, and Statue of Liberty) plus wooden cars. And, these pieces are all made from sustainable wood. A great addition to any NYC kid’s playroom. Buy it for $16.50 at The Museum of Modern Art.
