4-Piece Aluminum Alloy Geometry Ruler Set | Multifunctional Drawing Ruler with Stencils | 15cm Straight Ruler, Triangle Ruler, Protractor | Purple Metal Scale Ruler for Drafting & Art

This four-piece aluminum alloy student ruler set includes a straight ruler, two triangular rulers, and a protractor, designed for precise measurement and drawing. Crafted from durable aluminum alloy in a purple finish, these tools resist breaking and maintain their shape better than common plastic alternatives. The 15cm straight ruler features shaped cutouts—round, trigon, star, hexagon, and arrows—for use as a stencil in art, crafts, and assignments, while clear markings ensure accuracy. The protractor and triangular rulers have hollow structures for dead-angle-free measurement of angles and lengths. Rounded edges provide safety, especially for young students, reducing injury risk. The set comes in a compact box (16.5x7x1.5cm) for easy storage and portability, making it a suitable gift for graduations or festivals. Net weight is 80g, with package dimensions of 6.5x2.56x0.59 inches.
