Multi pens is just what it's called - multiple pens in one. Below this category you will find a whole host of combinations! For example, a pen can consist of one or more pencils along with ball points in different colors. Pencils, ballpoint pens and markers are also combined. If the multi pen contains more than one point, the ink will have many different colors and is also refillable. Imagine what inventive people can push into one and the same pen! The combination makes the switch between writing, sketching or marking more than available.
