Harfington 2pcs Folding Straight Rulers 30cm Metric Aluminum Alloy Protractor Foldable Ruler Geometric Measuring Tool with Angle Line for Architects Artists Office 2 Colors

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.
