Abstract
A marking pen assembly includes two or more colorant supply units and a colorant applicator detachably connected together, so that when the pen assembly is stroked along a work surface plural parallel strips of colorant are simultaneously formed on the work surface. A connecting mechanism between the colorant supply units is designed so that the units can be separated from one another and used as individual marking pens. The marking pen assembly enables the user to obtain a rainbow coloring effect with a stroke of the pen assembly.
