Disappointed!
I am a little disappointed with this toy, which I bought for my 3 year old. She loves playing with the shapes. However, the pieces did not stick well to the black cardboard at all. I saw this in another review so perhaps I will call the manufacturer. The spiral bound book also fell apart literally on the first use. I am surprised it was not better constructed.

Limitless creative value
I was there when the first edition was released. It was magical then and when I opened the very attractive box of my new version, it was magic all over again. No guidelines, two background boards, bright basic primary colored shapes; it's tantamount to having a nice building block set in your lap. Use on mirrors, windows, and other smooth glass-like surfaces to unleash new energies. It would be even more fun to have extra colorform pages from which to cut one's own shapes. I rate my Colorforms with an A+.

Great for a creative kid!
The first day was fun for my 4 yr old. He does not like to clean up - ya, ya, I Know he should... so we have started to loose the smaller pieces. Now, he finds it difficult to pick the smaller pieces and always wants company when he does this. Infact, my 10 year old does get carried away with this toy. This set should have more project pictures. I bought three and will pass them on as birthday gifts.

Good, but 2 year old too young
Got it for our two year old...probably not ready for it yet, so we are putting it away until her imagination and dexterity increases.

Designed by artists, perfect for making art
I read that Colorforms were designed in the 1950's by two artists who were looking for a fun way to decorate the walls of their apartment, and the artistic foundation of this product is clear. While Colorforms don't stick to walls, they do stick very lightly to completely smooth, clean surfaces like tile, glass (windows), and whiteboards, and they are so fun for all ages to play with. My 2 year old loves them, and the set is huge: 70 shapes of different sizes in 5 colors, a total of 350 pieces. The set offers great potential for learning about shapes and making imaginative compositions. I showed my child how two triangles can make a star or a diamond when put together in different ways, and she is fascinated. Putting the shapes back in their places is also a fun learning experience. Colorforms allow young children to make designs easily, like a house, that they can't make well with crayons yet. Best of all, Colorforms wipe clean and never wear out. A+
