Summary

This is an easy and convenient way to, for example, make a graph on graph paper. It can measure boxes on graph paper, and inches on the back. The pencil guide is 20 graph boxes long, making useful for making a graph that goes 10 in each direction, as well as making straight lines. I'm doing a lot of this in math, and I hope it helps some of you all.

NOTE: The 5x5 and 4x4 models are different. 5x5 means there are 5 boxes per inch, and 4x4 means that there are 4 per inch. Make sure you measure before you print!
