Fat Brain Toys Spiroku

This is not a typical stack-and-nest toy. The weirdly shaped pieces can be stacked and arranged any way you want. But then, nest them together, pull up on the smallest and let your jaw drop. The whole thing stretches into a tall, spiraling tower! Beautifully un-ituitive design inspires hours of tactile discovery. Age: 3 years and up Size: 55.88cm tall when stretched into a tower. Largest cylinder measures roughly 10cm in diameter. Contents: 9 cylinders sized big to small. High-quality ABS plastic - BPA-free. Encourages fine motor skills, spatial reasoning, experimentation, creativity.
