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 the accuracy of measurement and angle drawing.The angle scale is clear and the angle value can be read intuitively, preventing reading errors and improving work efficiency.Folding design takes up less space and is easy to carry and store. - Applications - Widely used for geometric drawing, floor plans, composition planning, mathematical chart drawing, etc., suitable for work environments such as classrooms, architectural design, art design offices, etc. where precise measurements and drawings are required. - Caution - Please avoid colliding the folding ruler with hard objects to prevent damage to the scale and affect measurement accuracy.Please do not bend the folding ruler to maintain accuracy and stability.
