The Color Wonder-Invisible Ink series allows colors to magically appear only on the special coloring pages. It includes special markers that reveal their ink only on the special pages included.

The package contains 18 special coloring pages featuring characters and images from the PJ Masks series. It also includes 5 special markers (red, yellow, blue, green, orange) that write only on the Color Wonder special coloring pages.

Note: Color Wonder products are invisible on most surfaces, but in some special cases, certain surfaces may be affected by the color. It is recommended to test the markers before using them on a spot where children will play.
