Professional Set Square

I bought both the centro 25cm and the 32cm as a gift for my wife who is into geometric design and Islamic architecture, which requires very precise and accurate point placement. seeing how much she was struggling with parallel lines, I went and ordered these for her knowing I was buying the best there is. the Rotring brand is well known among artists and architects and I remember some of my architect friends using it for their drawings. it did not disappoint. my wife was elated by how accurate and precise it was. great product all in all.

Helps with perspective drawing.

I love this product. Sounds sad, I know, but it’s my most used item in my drawing kit. Very sturdy, easy to read and has clean sides, no bumps to spoil your lines. Terrific item.

I like the large size. The handle is a bit tricky to slide in the slots but once done, stays there. Very pleased

the grader is smaller than my original grader but do like the extra measurements also the hand grip great idea. as for the glass beads i purchased they are beautiful with a high shine

Well worth the price and extremely accurate for geometric measurements.

This square stays in place, casts very little shadow from the edges, and is very precise for drawing a line that is perpendicular to a ruler or Another line. It is not small and probably not optimal for paper sizes < A3

Ok but handles tend to pop off sometimes
