Reusable Brow Proportion Guide

This 5 cm (1.97 inch) eyebrow ruler is made from flexible, wear-resistant PVC with an ergonomic curved shape and clearly visible scale markings. Its smooth surface ensures comfortable handling and reliable grip during use, while its light weight and compact dimensions make it ideal for storage and portability. Designed around standard facial proportion logic, the ruler helps locate the natural beginning of the brow at the inner eye’s vertical line, the arch directly above the outer edge of the iris, and the tail extending to the outer eye corner — enabling consistent, flattering shape definition. Used at home for daily maintenance, in salons for efficient client assessments, and on-the-go for last-minute corrections — this tool bridges the gap between DIY convenience and professional-grade accuracy.
