Colorforms is one of the best examples of how the simplest of things can be the most enchanting for kids. The original colorful vinyl shapes have remained popular since their invention more than 50 years ago. They were one of my obsessions when I was young, and I still love playing with them with my daughter. While they come with both black and white background boards, Colorforms also adhere well to appliance surfaces (refrigerators, dishwashers, etc.) and car windows without leaving a mark, which also happens to make them an incredibly versatile “toy”, both at home and on the go.
