Each of the five cups features a squishy silicone bubble embossed with its own unique texture, inviting curious hands to touch, push, and explore. Beyond the sensory appeal, these cups stack big to small or nest small to big, turning playtime into a hands-on discovery session that grows with your child's abilities.
