We bought two plastic travel boxes with the Color Wonder markers and Color Wonder coloring books in them for our children to use in the car on long trips. Our oldest at 4 years old is very neat so we haven't needed anything like this before. But our youngest at 1.5 years old is one of the messiest children I've ever known. She gets markers all over her much less everywhere else! And she loves to color, draw, paint, etc. So this is the perfect thing for her to express her artistic side without all the worry of her getting it everywhere and damaging carpet, furniture, computers, etc. She is learning to be careful with these without us having to be too strict on her use. It is a great tool when teaching your child to be careful and neat with markers. It is great to have in the car as well because it won't damage the carpet or upholstery while you're riding down the highway without any knowledge of the rogue marker without its cap being thrown into the floorboard amongst other toys. The children think it's really neat that the markers take a few seconds to change color on the paper. It is quite expensive for the special paper, which the markers only work on.
