Positioning Pen with the Straight Edge

| View Cart ⇗ | Info

To draw a straight line, the pen must be perpendicular with the straight edge ruler, as shown in A. A one sided ragged line will result if the pen is positioned at C. If the pen is positioned at B, the ink will run under the edge and form a blot.
