Architectural Drawing Equipment By Leinuosen

• Material: the scale ruler set is made from pure aluminum mixed with other elements to create a high-strength alloy, and the triangular ruler is durable, lightweight and reliable
• Target customer: with reliable construction and accurate performance, the black construction ruler is appropriate for architects, engineers, draftsmen and students
• Relative advantage: aside from the laser-etched markings that won't rub off or fade, the ruler itself is made of solid anodized aluminum, unlike flimsy alternatives that contain plastic
• High contrast: white-on-black design makes each line and number significantly easier to read, ultimately preventing unnecessary eye strain
• Package includes: 6 pieces in total, which contains 2 packs 12 inch aluminum triangular architect scale rulers and 4 pieces aluminum triangle ruler square set
