Setup, Compatibility & Care
This ruler requires no assembly or configuration; it is ready for use immediately upon unboxing. To maintain the precision of the etchings and the integrity of the edge, keep the ruler in a dedicated storage slot or flat on your desk. Avoid dropping the ruler on hard surfaces like concrete, as a bent corner can ruin the ruler's ability to lie flat against your drafting paper. To clean, use a soft, dry cloth to remove pencil graphite or ink residue. If the ruler becomes damp, dry it immediately with a soft cloth to maintain the anti-rust finish.
