Fisher-Price Peek-a-Blocks Sensory Stacking Blocks

These classic Fisher-Price Peek-a-Blocks are such a great find for any little one. Each block has something different going on inside—some have spinning parts, others have little figures or textures, and they all make different sounds when you shake them. They're designed with those tactile ridges on top so they stack easily without sliding around. Used, but they've still got plenty of play left in them. It's a nice big set that'll keep a toddler busy for quite a while.
