Maker of Color Wonder Markers, I love your markers.
They can be used by all of my children without worry. You see the markers only work on the special color wonder paper. No need to worry about the little ones writing all over everything.
However I have one suggestion. When making other types of Crayola markers, such as the Neon Color Explsions, could you please make the difference stand out, from let's say... across the room?
This afternoon, from across the room, these looked the same to me.
