Little fingers can't resist these beautiful buttons! Built safely into the sturdy plastic frame are five vibrant silicone bubbles in varying sizes and colours. It's so simple, yet oddly, so brilliantly fun, fascinating, and impossible to put down. Push them all the way in to pop them through to the other side. It's a perfect sensory adventure kids can take with them everywhere they go! Bubbles made of 100% food-grade silicone. BPA-Free, fully safety tested. 6 months.
