## Long description

GDD 3D 45° set square, 13 cm length, sold as a pack of 25 pieces. This transparent triangular ruler provides a fixed 45° angle for drawing and measuring and is designed for classroom, office and craft use. The compact, lightweight design makes it easy to carry in pencil cases or tool kits, and the clear material allows precise alignment with underlying drawings and scales.
Advantages

How to use
Place the set square on the drawing surface with the desired edge aligned to an existing line or point. Use the fixed 45° angle to draw perpendicular or angular construction lines by running a pencil along the appropriate edge. For measurement, align the ruler edge with the scale on the drawing or use it as a straightedge for marking. When using on paper, hold the set square steady with one hand to avoid sliding and lift carefully to prevent smudging.
Usage recommendations
Store the set squares flat or in a protective sleeve to prevent warping and scratches. For group use in classrooms, distribute one piece per student to ensure consistency in teaching activities. Clean with a soft cloth and mild detergent if necessary; avoid high heat to preserve transparency and dimensional stability.
