Tulu by MOLUK 9 pc set

My three-year-old figured out how to nest them inside each other on the first try, and now we use them for everything from sorting games to building towers. The soft plastic makes them easy for small hands to grip, and they roll unpredictably enough to keep a toddler chasing after them.

The colors are so cheerful that my kids immediately started stacking them into a little tower before I could even read the box. They roll smoothly across the floor, and I love that we can mix them in with our other blocks for even bigger castles.

My toddler figured out how to nest all nine pieces in under two minutes, and now they're her favorite bath toys. The different shapes really let her imagination run wild, whether she's stacking a tower or rolling them across the floor.
