Precision curved measuring ruler for facial mapping and general curved measurements This curved ruler is designed to measure rounded and irregular surfaces with greater accuracy than a straightedge. It provides a clear, repeatable reference when positioning facial features for cosmetic procedures and for other tasks that require accurate curved measurements. Key benefits More accurate on curved surfaces than a straight ruler, reducing guesswork when measuring circumferences or arcs. Facilitates facial mapping by showing eyebrow position up and down, length, height and spacing to aid symmetry checks. Compatible with microblading, micropigmentation and permanent makeup workflows as a visual measuring aid. Quick to position on the face for fast, repeatable readings during layout and marking stages. Simple, handheld design suitable for use alongside common measuring tools and cosmetic instruments. How it helps Improves the consistency of layout and alignment by providing a direct visual guide for left and right comparisons. Speeds setup by allowing technicians to confirm placement and proportions without complex tooling. Doubles as a generalpurpose curved measuring tool for small craft, design and fitting tasks. Typical use scenarios Eyebrow mapping for microblading or micropigmentation: measure brow start, arch and tail to achieve a balanced layout before pigment application. Eyeliner and lip shaping: check length, height and symmetry to align markings on both sides of the face. Noncosmetic measuring: measure rounded edges and circumferences on small objects or craft pieces where straight rulers are inadequate. Notes on compatibility and use Intended as a measurement and alignment aid to be used alongside standard cosmetic tools and techniques. Quick to position and read, making it practical for repeated checks during procedures or fitting work.
