This Vinca 8" x 12" steel frame is a sturdy square. The square is made of steel which has some weight to stay in place and not move. Markers are stamped and epoxy coated to resist rust. The coating leaves a glossy, smooth surface that reflects light, and blackening the markings would improve visibility. I mainly use it as a guide for adjusting the patterns, so I don't really care about the stamped marks, but the numbers are big and easy to read in good light. What I need in a square is accurate alignment, and my Winck square is very accurate in that regard. This is a good standard frame square at a great price.
