Four sizes offer versatility for block play, dramatic play, and even extra seating. When not used, the closed platform-like boxes nest inside the open crate. Once they're out, the sky's the limit for how kids will incorporate them into their play. If you need a seat for a rocket ship, a bed for a doll, or a platform to step on to reach a tall block tower, reach for one of these boxes! We know that toddlers love to go up and down every staircase they come upon; now, you can build one to last for a few minutes, hours, or days. Unlike traditional hollow blocks, these Nesting Boxes occupy very little storage space.
