Aluminum Alloy Drawing Ruler Set • 4-Piece Metal Ruler • Straight Ruler • Triangle Ruler • Protractor • 15cm Hollow Stencil Ruler • Red

This four-piece aluminum alloy ruler set includes a 15cm straight ruler, a protractor, and two triangular rulers, meeting all basic measurement and drafting needs for students. Crafted from timeproof aluminum alloy, these tools are far more durable and resistant to breaking than common plastic rulers, ensuring long-term shape retention and reliable use. The straight ruler features a hollow design with cutouts in shapes like circles, triangles, stars, hexagons, and arrows, allowing it to double as a stencil for drawing patterns in art projects or academic assignments. Its clear markings enable precise measurements, while the hollow protractor and triangular rulers allow for dead-angle-free angle and length readings. Rounded edges prioritize safety, making them ideal for young students. Packaged in a compact, portable box, this set is easy to organize, store, and carry, making it a thoughtful gift for graduations or holidays.
