Setup, Compatibility & Care
This ruler is ready for use immediately out of the packaging. No calibration is required as the markings are factory-set for high precision.
Compatibility: It is compatible with all standard writing instruments, including graphite pencils, technical pens, and markers. It fits comfortably in standard pencil cases or desk organizer slots.
Care Instructions:
- Cleaning: Wipe the surface with a soft, lint-free microfiber cloth. If markings become obscured by dust or oil, a damp cloth with mild soap is sufficient.
- Storage: Store flat or in a vertical sleeve to maintain the ruler's original straightness. Avoid leaving the ruler in direct, high-heat sunlight for extended periods to prevent potential material deformation.
- Handling: Avoid using high-heat heat guns or abrasive scrubbers, which could dull the transparent finish.
