Achieve absolute geometric precision in every layout. Whether you are an architect mapping a new structure or a student mastering trigonometry, the Staedtler Mars Professional Set Square provides the crystal-clear visibility and unwavering edge stability required for flawless technical design.
Master Every Angle with Clarity
Stop guessing your line placement. This 8-inch drafting tool is engineered from high-grade transparent acrylic, giving you an unobstructed view of your grids and previous pencil strokes. It transforms complex drafting into a smooth, distraction-free creative process.
The integrated bevelled inking edge lifts the tool slightly off the paper, preventing ink smears and bleeding when using technical pens or markers.
At 2.5mm thick, this set square is built to resist warping and movement, ensuring your 30°, 60°, and 90° angles remain true over years of use.
Premium optical-grade acrylic allows you to align your work perfectly with underlying templates without the visual interference typical of cheaper plastics.
Designed to work seamlessly with standard drafting boards, T-squares, and high-precision technical drawing pens.
