Instructions are fairly easy to understand but I'm not so sure younger kids would get the hang of it. The suggested age level for this 3D set is 8+ and I think that's appropriate.
To create a 3D piece of art, you first need to twist on one of the marker tips on to the marker you want to use. Then you need to slip the LED light on to the marker. It doesn't stay securely in place, so you have to use your thumb to keep it on. Then you turn the light on. The batteries for the light are already included, so that's a plus. It is important not to look directly in to the light.
As I mentioned before, the book includes project templates. Once you've chosen the one you want to work with, you need to place the clear plastic sheet on top of that specific project. Then you use the pen with light to trace the pieces. My first creation was a pair of sunglasses. It was easy enough to trace but required precision and a slow, steady hand. To ensure that the material hardened as needed, I had to go over the pieces a couple of times with the LED light.
My finished projects didn't come out perfectly, but it was fun enough to play with.
