Blockaroo magnetic foam builders are the easiest building system for young learners ever created! One of the things that makes Blockaroo blocks truly special is the innovative magnetic system, which allows the blocks to connect like magic, every time. Blocks never repel each other, creating endless possibilities for play. The non-toxic magnetic blocks also rotate 360-degrees when connected and click when they turn, providing even more opportunities for interactive and creative fun! They are also a phenomenal STEM toy that grows with your child. They teach important early STEM skills such as counting, sorting, and stacking for toddlers while stimulating tactile and sensory development. When children are a little older, they promote engineering and creative thinking skills. They were developed by teachers and are safety tested to exceed the highest international toy standards. And these blocks are great in the bath too! The foam bricks float and even stick to most bathtubs due to the metal liner common inside most tubs. They keep kids learning and having fun in the bath, transforming bath time into an experience parents and kids look forward to! The 10-piece robot set includes everything your child needs to build an exciting bot! And after that, they can use the blocks to invent their own unique creations. 10 pieces. 18+ months.
