However, due to the small size of the balls and the risk of accidental ingestion, it is suitable for children aged 7 and over. [Educational] This is a great toy that encourages thinking about the assembly and route of the 3D blocks, allowing children to use their brains in various ways, rebuilding through trial and error, and building with their imagination. While considering the 3D structure, you have to think about how to thread the ball. With so many parts, you have to consider the various shapes and balance, making it a very intellectually intensive game. It's huge! Assembling and disassembling is also a fun part. It's a great toy that parents and children can enjoy, and it's great for developing creativity and dexterity. The simple shapes of the blocks will bring out your child's creativity without limit!
