Product Information
Full details
The Staedtler Mars Metal Ruler (563 30) is a high-precision 30cm measuring tool designed for students, technical artists, and professionals who require consistent accuracy. Crafted from durable aluminium, it offers a robust build that withstands the rigors of daily use in a studio or classroom, with a key benefit being its specialized inking edge that prevents messy smudges. A notable caveat is that while the metal construction is exceptionally durable, the ruler is rigid and should not be bent or used on curved surfaces.

Setup, Compatibility & Care
This ruler requires no setup out of the packaging; simply place it on your workspace to begin. It is compatible with a wide range of writing instruments, including technical pens, mechanical pencils, and standard markers.
To care for your ruler:
- Cleaning: Wipe the surface with a soft, dry cloth to remove pencil lead dust or paper fibers. If ink gets on the edge, a damp cloth with mild soap is sufficient.
- Storage: Store flat in a drawer or a pencil case. Avoid keeping it in tight, high-pressure environments that could bend the thin aluminium structure.
- Maintenance: Check the non-slip pad periodically; if it collects dust, wipe it down to maintain its grip strength.
