Aluminum Alloy Drawing Ruler Set - 4-Piece Geometry Kit, Straight Ruler, Triangular Rulers, Protractor | Metal Scale Ruler for Precision Measurement

This 4-piece aluminum alloy ruler set offers students a durable and versatile drafting solution, combining a straight ruler, two triangular rulers, and a protractor in one convenient kit. Crafted from timeproof aluminum alloy, these tools resist breaking and maintain their shape longer than common plastic alternatives. The 15cm straight ruler features various shaped cutouts—including circles, triangles, stars, hexagons, and arrows—that double as stencils for drawing patterns, while clear markings ensure precise measurements for assignments and art projects. The protractor and triangular rulers incorporate hollow structures that eliminate blind spots, allowing accurate angle and length readings without dead angles. Safety-oriented rounded edges prevent injuries during use, making this set ideal for younger students. Each piece is packed in a compact, portable box for easy organization and storage, making it a thoughtful gift for festivals, graduations, or everyday academic needs.
