The tip of the pen is rigid and it will draw differently depending on the pressure used by the artist. Always try to keep the same amount of pressure throughout the drawing otherwise the lines will not be proportional. There are different sizes in tips to regulate the size of the line that is drawn: from 0,1 to the most fine tip 2.0. The pens’ tips of the pens are very fragile, they should be used carefully and on smooth paper.
