Uxcell Folding and Straight Ruler Kit 30/15cm Metric Aluminum Alloy Protractor Foldable Angle Wave Edge Ruler with Hollow Circle for Home Classroom Office, Blue-Gray

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 geometric ruler adopts a center rotation design, ensuring stable rotation for precise angle measurement and drawing. The clear angle scale allows intuitive reading, minimizing errors and improving efficiency. Its folding design saves space for easy portability and storage. The straight ruler features a wavy stripe edge and five circle templates in varying sizes for marking or drafting. The aluminum ruler kit is widely used in geometric drawing, plane drawing, composition planning, and chart drawing; it is suitable for classrooms, architectural design, art design office occasions, and other work environments that require precise measurement or drawing. Try to avoid collision of the 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.
