Rainbow Sand Blocks - 8 Pieces

My little one is obsessed with stacking these blocks, and the way the colors blend when you hold them up to the light is so cool. They're solidly built, too, and the sand inside makes the softest rattle noise that keeps her entertained for ages.

My 2-year-old spends forever stacking these and watching the sand shift through the colored frames—the sound they make when tapped together is oddly satisfying. They're sturdy enough for some serious toddler handling, and I love that he's learning colors while he plays.

My toddler can't stop shaking these to hear the sand rattle—the sensory sound is such a fun twist on regular blocks. Stacking the different colors together to watch them blend through the clear frames keeps her engaged way longer than our old plain wooden set.
