1. KEY FEATURES: - Size - Measuring range: 30cm; System: Metric; Minimum graduation: 1mm; Thickness: 3mm; Width before folding: 21mm; Width after folding: 29mm; Package includes: 1 folding straight ruler. - Material - The office ruler is made of aluminum alloy, hard and durable, not easy to deform or damage, ensuring measurement accuracy.The lightweight aluminum alloy ruler is flexible and convenient for one-handed operation and long-term continuous measurement.The anodized surface effectively prevents corrosion and rust on the aluminum alloy surface, extending the lifespan of the folding ruler. - Features - The geometric ruler adopts center rotation design, which is more stable when rotating, ensuring accuracy in measurement and angle drawing.The angle scale is clear and the angle value can be read intuitively, avoiding reading errors and improving work efficiency.Folding design takes up less space and is easy to carry and store. - Applications - Widely used for creating geometric drawings, floor plans, composition plans, and mathematical diagrams, suitable for classrooms, architectural design, art design offices, and other work environments where precise measurements and drawings are required. - Caution - Please avoid colliding the folding ruler with hard objects to avoid damaging the scale and affecting measurement accuracy.Please do not bend the folding ruler to maintain accuracy and stability.
