Little fingers (and big ones alike) can't resist these beautiful bubbles! Built safely into the sturdy ABS plastic frame are five vibrant, 100% food-grade silicone bubbles in varying sizes and colors. It's so simple, yet so brilliantly fun, fascinating, and impossible to put down. Push them all the way in and they audibly pop through to the other side. Delve into the simple delight of poking them with your fingers like never-ending bubble wrap! It's a perfect sensory toy that kids can take with them everywhere they go!
