The definitive tight 3 needle grouping. This grouping, made with three long taper #10 needles pulled very tight, nearly mimics a single when used with a light hand and grey wash. More importantly, it puts in incredibly clean lines and resists blow outs that often plague tight, and small needle groupings. This is not just my opinion and experience, but also shared with others who have used them with great occasion. Its amazing to use such a delicate needle and not sweat every line, anxious of blow outs. They also allow the user to end lines with perfectly diminishing weight by adjusting the needle depth. Amazing for delicate script, these also work great for those of you who like to do shading with really small needle groupings. These are absolutely THE BEST super tight grouped threes made.
