The Zotemo 5-piece set is a professional-grade drafting kit that features components made from 6061-T6 aluminum alloy. This material switch from plastic to metal significantly mitigates common issues like edge-chipping and warping. The tools have a matte black anodized finish, which is designed to reduce glare under bright lights, providing a clear ergonomic benefit for students and professionals alike.
The markings on these tools are laser-ablated, meaning they are physically recessed into the alloy for permanent legibility that won't rub off over time. With a torsional rigidity much higher than plastic, these rulers and triangles will not snap under the pressure of a heavy backpack. The set maintains a high level of geometric accuracy, making it suitable for everything from K-12 education to vocational drafting and light technical engineering projects.
If you also need a compass to go with your metal rulers, the Mr. Pen 15-piece set includes both metal rulers and drawing instruments.
