Soft, intriguingly textured, but graspable, and if you give them a shake, you'll discover a soothing chime inside! There is much to explore with Fat Brain's Sensory Rollers, and babies will spend hours rolling them around, bouncing them, picking them up, and just feeling their interesting surfaces. Sensory Rollers are a great way for growing babies to work on their motor skills, their tactile senses, hand eye coordination, and auditory skills, all while staying entertained. The plastic used is soft and BPA free. Recommended for children ages 6 months and up. Imported.
