Safta | Classic School Triangle, Transparent Glass Ruler With Centimeter Scale, School Ruler For Technical Drawing For Back To School, Transparent Glass Type Material

School set squares from the Classic Stationery line, designed for daily use in class, at home, or in the academy. This set of variants includes set squares with a classic design, with a transparent crystal-like finish and also in green, to choose the style that best fits each pencil case and the working method of each student. Its rigid and flat format is aimed at providing a stable guide for drawing lines, checking angles, and supporting the pencil or marker with control, especially useful in technical drawing, geometry, and precision tasks in notebooks and pads. These stationery set squares are available in a length range of approximately 20 to 30 cm, allowing them to adapt to different sheet sizes and school levels without changing tools. The transparent material makes it easy to see the stroke and the text underneath while aligning the ruler, helping to place it accurately before marking. The straight edges are designed for smooth sliding over the paper, and their rigidity helps them maintain their shape with regular use in the school backpack. They are a practical complement for pencil cases and pouches, and fit well as basic back-to-school material alongside rulers, compasses, and protractors. Recommended for boys, girls, and students who need a reliable set square for geometry, drawing, and crafts, both in primary and higher courses. To keep them in good condition, it is advisable to store them flat in a folder or in the main compartment of the school backpack, avoiding bending them or placing them under heavy objects. Cleaning is simple: just wipe with a slightly damp soft cloth to remove graphite or ink residue and maintain transparency.
