Bought these for my 2-year old grandchild, who spends a great deal of time building flowers by matching the inside color of the flowers to the outside color of the flower petals. It's a nice change from building with legos. I supervise because I didn't realize until they arrived that they are intended for children 3-years and older. I had to use a plastic container for storage because the box is just basic brown with a color sleeve that slides over it containing flower images....
