Non-slip with black markings. Unique pivot point; angle markings to easily make 15-30-45-60-90 degree cuts. Easy to read numbers and gridlines. 1in grid with 1/2in, 1/4in, and 1/8in increments.

I love the fact that there are no green bubbles, no yellow outside of black, no big black or white circles...just clear, non glare, and easy to read!
