相反球

My little one loves figuring out which ball is heavy and which is light before tossing them across the floor. The contrasting textures keep her engaged way longer than I expected from simple balls, and they're sturdy enough for daily play.

Took these into the bath and they're perfect for water play, plus the weight difference between the light and heavy ones is really obvious to my toddler. He's learned "in" and "out" just by watching them float or sink.

My one-year-old loves grabbing these during bath time, and the light-versus-heavy pair is such a clever way to introduce the concept without any words. They’re the perfect size for little hands and hold up great to splashing.
