Non-Graffiti Pen

Painting is children’s nature, though always loose control. Parents are happy to see children' painting on paper with full of imagination, but it is annoying when children paint on the wall.
Non-Graffiti Pen uses a special structure. The ink inside the pen will coms out unhindered when child writes on the paper vertically. However, the ink doesn’t flow while child is writing on the wall horizontally.
