Protractor with a graduated semicircle and an articulated arm fixed at the center by a pin: the arm rotates along the graduated scale to measure and transfer angles onto paper, wood or other materials. The scale engraved on the edge allows quick readings, while the extended arm with a hole at the end makes it possible to draw inclined lines precisely. A flat, lightweight tool, suitable for technical drawing, carpentry, DIY and measurement work in general. Dimensions: 12 cm
