One of the most important things to remember when storing pens and markers is to store them horizontally so that the ink flows evenly. Most people may be inclined to buy containers that stand vertically, but storing them this way will make all the ink flow to one end. If the ink is at one end of the pen or marker they may not last as long or work as well. Storage drawers will allow the markers and pens to be stored horizontally. You can leave your markers in their original box and store them in a desk drawer or plastic organizer drawer.
