    Great engineering paper!

    Posted by Ben G on Aug 9th 2025

    This paper is awesome. The lines are subtle enough to disappear when photocopied but visible enough to be easy to use. Every 5 squares is a bolder line, so it's easy to navigate the grid. The texture and weight of the paper are great, smooth and not too heavy or light. I highly recommend this paper!
