Great Idea, Not-So-Great Execution
The fact that these markers only write on the special paper is brilliant and a true sanity-saver for parents, especially on airplanes and long car trips or in restaurants, but BOO! to Crayola for making the coloring books so it's impossible to draw outside the lines on the pictures.

One of the many reasons coloring is such a great activity for kids is that it helps to develop their fine motor skills as they learn to control their hand and keep the color within the lines, but with these coloring books marks outside the lines are invisible, which means it's nearly impossible for the child to see for themselves how well they're controlling the marker.

And then when kids want to deliberately color outside the lines, their creativity is stifled. For example, my 3-year-old wanted to draw a hat on one of the animals' heads the other day, and wound up confused and very frustrated by the fact that it wasn't possible. She had to switch to crayons to do what she wanted, which is fine, but it sort of begs the question: Why bother with the markers in the first place?

Crayola does make pads of plain, picture-free paper for the Color Wonder markers, where you can write on the entire surface of the sheet, and those are very good for drawing and writing. But for coloring in pictures we'll stick with regular coloring books and Crayola's washable markers and crayons from now on, which have the added benefit of being far less expensive than the Color Wonder stuff.

What a WONDERful idea!
These markers are the greatest invention EVER! My son loves to take of the tops and put them back on, in addition to coloring the pages. I wish each side of the pages was colorable. Pretty expensive product, but worth it for not having marker all over everything!

Great toy!
I recently purchased these markers for my 19mo old son. He likes to draw with markers and not crayons. He was fairly good with markers but would accidentally (really!) get markers on his clothes, hands, the table etc...
Then we bought these! They are wonderful! He can draw to his hearts content and not get marker anywhere but the paper...
Plus, it's neat to watch the marker "appear" on the paper! It doesn't appear instantly but fades in... very nice!
It's about time someone thought of this!!

CRAYOLAS GREATEST INVENTION!
I HAVE 4 KIDS. THEIR AGES ARE 5, 4, 2 AND 1. ALL OF THEM LOVE TO DRAW AND COLOR BUT THEY JUST CANT SEEM TO KEEP REGULAR MARKERS OFF THE WALLS, THEIR CLOTHES AND THE CARPETS. I SEEN THIS AT THE STORE AND DECIDED I WOULD TRY IT. IT IS THE BEST! ALL OF MY KIDS INCLUDING MY 1 YR OLD CAN USE THESE WITHOUT MAKING A MESS. THESE MARKERS WILL NOT DRAW ON ANYTHING EXCEPT THE SPECIAL CRAYOLA PAPER THAT COMES WITH THE KIT. WHEN YOU RUN OUT OF PAPER YOU CAN EASILY GET A REFILL FROM THE STORE. THIS IS A VERY INEXPENSIVE GIFT THAT KIDS WILL LOVE AND SO WILL YOU!

Crayola Color Wonder is Wonderful
My 3 year old received this for her birthday. It is the greatest set of markers I have ever seen. No messes on table tops, carpets, walls. Even my 3 year old colors oerfect pictures since you can't color outside the lines. My kids love this toy.
