Unique Bargains Folding Straight Ruler 30cm Metric Aluminum Alloy Protractor Foldable Angle Ruler Geometric Measuring Tool with Angle Line for Architects Artists Office Pink

Size - Measuring range: 30cm / 11.81"; system: metric; minimum scale: 1mm / 0.04"; thickness: 3mm / 0.12"; width before folding: 21mm / 0.83"; width after folding: 29mm / 1.14";

Material - The office ruler is made of aluminum alloy, which makes it hard and durable, not easy to deform or damage, ensuring measurement accuracy; the lightweight aluminum alloy ruler is more flexible to operate and convenient for one-handed operation or long-term continuous measurement; The anodized surface can effectively prevent the aluminum alloy surface from corrosion or rusting, extending the service life of the folding ruler.

Feature - The geometric ruler adopts a center rotation design, which is more stable when rotating, ensuring the accuracy of measuring and drawing angles; The angle scale is clear, and the angle value can be read intuitively to avoid reading errors and improve work efficiency; The folding design takes up little space and is easy to carry and store.

Application - It is widely used in geometric drawing, plane drawing, composition planning, and mathematical chart drawing; it is suitable for classrooms, architectural design, art design office occasions, and other work environments that require precise measurement or drawing.

Note - Try to avoid collision of the folding ruler with hard objects to prevent damage to the scale and affect the measurement accuracy; Please do not bend the folding ruler to maintain its accuracy and stability.
