This is a refill pad for the Crayola Color Wonder™ Activity Set.
No pens are are included in this pad. It is just a shrink-wrapped booklet containing 18 pages each 8.6" x 10".
The pages are the special "Color Wonder" technology which allows you to reveal the color picture by applying the magic chemical from with the Color Wonder pens, all thanks to a patented interaction between two complementary phenol-formaldehyde compounds.
The artwork is taken from the Ultimate Spider-Man TV (2012) series.
Have you have seen one of those "paint with water" books? We have a couple of them listed on the site. You can color a picture with just water, and when it dries out, the picture fades and you can color it again.
"Color Wonder" is just like that, except with DRM protection.
Kids love this stuff. Crayola sells a crap-load of it, based on an endless series of Disney products. I have to admit, the quality of the product is absolutely top-notch. Crayola does not skimp on production values.
I guess it is what it is. Three Webs.
