Little fingers can t resist these beautiful buttons! Built safely into the sturdy ABS plastic frame are five vibrant silicone bubbles in varying sizes and colors. It s so simple yet oddly so brilliantly fun fascinating and impossible to put down...for babies...or adults! Push them all the way in to pop them through to the other side. Delve into the simple delight of poking them with your fingers. It s a perfect sensory adventure babies and toddlers can take with them everywhere they go! (Not to mention it s also a great decoy for staving off your grandma s cheek-grabbing fingers...)
