Holes: Each hole acts as a measuring device. 5 holes=2 inches. These are also great for extra grip and control.
What Makes This Comb Special?: This comb has a flat top for measuring 90 degrees anywhere on the head. Not only that, but the teeth are concave shaped, which allows the comb to sit more comfortably in your hand. Similar to our G20 comb, but without the measurements.
