• No need to change the top and bottom! Unlike 3way marker/conventional twin marker, 3 types of lines can be drawn with a single tip like a beetle horn: thick line, thin line, double line (enclosing line). You don't have to switch the top and bottom of the pen to use different nibs.
• Double lines in character enclosures/double lines that can be marked to enclose characters are recommended when copying. The color of the marker does not cover the text, so you can keep it easy to see.
• Based on the winner of the Kokuyo Design Award (2007 Excellence Award), this product was arranged into a standard that is easy to use everyday.
