Blockaroos were developed by teachers and are the easiest construction toy for preschoolers ever developed! Blockaroo Blocks are a new way to build. These soft foam magnetic blocks click together like magic, rotate 360-degrees, and always attract to each other, creating a multi-sensory experience. They also float which means that this unique construction toy doubles as the ULTIMATE Bath toy! Because they’re water safe, Parents love that they can easily sanitize these blocks in the dishwasher!
