These are essentially a 7, but have the center needle drawn back about 1cm, to allow for greater ink flow through capillary action. They are soldered in what most would consider a straight or "traditional" configuration, and lay dense black lines quickly. the line size is similar to a straight 7. Great for sculpting lines and for coloring in tighter areas fast and efficiently. Their Textured needles make them a little more aggressive than our Straight liner series.
