5220 ROLLER BRIGHT & COLORFUL: A rainbow color design makes this one of our most vibrant and visually stimulating toys for newborns. Explore each bright color as the Roller makes its way across a variety of surfaces! SUPPORTS EARLY DEVELOPMENT: An inner wooden ball inside of the roller makes a soft sound when the toy rolls across a surface. Babies can stimulate a variety of developmental areas during play - including their hand-eye coordination fine motor and sensory skills - as they grip grasp push and roll the Roller. BABY-FRIENDLY: Made of sustainable rubberwood and stained with non-toxic water-based dyes the Roller is free from harmful chemicals and sharp edges so babies can play safely.
