Transform complex visions into perfectly fluid shapes. Whether you are an educator teaching geometry or a professional designer drafting intricate patterns, the STAEDTLER Mars Flexible Curve gives you the manual control to plot, measure, and hold any unique contour with absolute precision and zero shape-drift.
Precision Engineering for Creative Freedom
Designed for those who demand more than a straight edge, this 18-inch (450mm) tool allows you to translate physical dimensions into technical drawings seamlessly. The integrated lead core provides the necessary friction to ensure that once you set a shape, it stays locked until you decide to change it.
High-visibility graduations in both Metric (mm/cm) and Imperial (inches) mean you can work on any project without stopping to convert units.
Raised ink edges on both sides lift the ruler off your surface, preventing technical pens, markers, or pencils from smearing your hard work.
The flexible plastic body is engineered to resist discoloration and brittleness, ensuring the core remains supple for years of daily use.
Proven reliable for use with technical pens, drafting pencils, and even fabric chalk for fashion pattern making and woodworking templates.
Why It Matters
Generic rules lack the internal stability to hold complex radii. STAEDTLER's metal ribbon technology provides professional-level shape retention, making it an essential tool for engineering layouts, cabinetry, and fine arts where a mistake in a curve means a mistake in the final product.
