A Ruler Set with Protractor (general geometry kit) is a compact, multi-piece measuring toolkit typically designed for students and young learners (ages ~6+). It includes a clear plastic 15 cm (6‑inch) ruler, a 180° protractor, two triangular set squares (30°–60° and 45° triangles), and often extras like a compass, mechanical pencil, eraser, sharpener, and storage pouch or case. These tools provide precise metric and imperial markings and are crafted from lightweight, translucent plastic with rounded corners for safe use. They support activities ranging from drawing straight lines and measuring angles to constructing basic geometric shapes and arcs—ideal for schoolwork in math and art classes while being easy to carry and store.
