    If your child comes up with an idea for an educational toolbox, we would be more than happy to help turn it into a real product, and your child will become one of our inventors. The inventors of the popular inventions will create their own Inventor's Toolboxes (with cartoons made of them to star in the books and on the boxes) to be sold through A Hundred Tiny Hands, with proceeds going back to the little inventors! So when parents buy an Inventor's Toolbox, you are not only buying an educational toy, but access to a scientific community and an opportunity for your children to invent real products.  Join the Tiny Hands movement and help us invent inventors.
