What a great needle, big and fun. It's like using a brush pen on a tattoo- amazing! Great for tiger stripes, rocks, coloring in anything you want saturated and interesting, as well as just making some big, powerful lines. They push color amazingly in part due to their textured needles. These lay down lines almost as big as a straight 14.

Hollow 10 is a needle for those who are looking for an even stronger, bolder line, with lots of ink flow. They also work quite magically as a round shader, packing it in and allowing you to dip less and thus increasing efficiency.
