## Long description

The Tetis two-arm set square BL003-B with a 10.5 cm arm length is a compact, precision drawing and measuring tool designed for marking and checking right angles, guiding straight lines and transferring measurements. Its small size makes it convenient for school use, technical drawing, hobby projects and light workshop tasks where accuracy and portability are required. The transparent construction permits clear visibility of the drawing surface and improves alignment when working with pencils, pens or fine markers.
Advantages
The set square offers accurate 90° angle checking and stable guidance for straight lines in a compact form factor. Its 10.5 cm arms provide both reach and control for small-scale tasks without sacrificing precision. Made from durable transparent material, the tool resists everyday wear while allowing easy visual alignment and measurement transfer. The lightweight design is easy to carry in pencil cases, toolkits or pockets for on-the-go use.

Key specifications
Arm length: 10.5 cm
Type: two-arm set square (right angle)
Material: transparent rigid plastic
Size: compact, pocket-friendly
Visibility: transparent for clear alignment
How to use
Place one arm of the set square flush against the reference edge or baseline. Align the other arm to the line to be drawn or checked to create or verify a 90° angle. Use the transparent body to position the tool precisely over existing markings and trace along the outer edge with a pencil or pen to draw straight lines. For transferring measurements, line up a measurement mark on the work surface with the corresponding position on the set square and move the tool as needed while keeping it firmly against the reference edge.
Usage recommendations
Clean the surface and the set square regularly to maintain visibility and accuracy; avoid bending or exposing the tool to high heat. For precise technical work, combine the set square with a straight edge or ruler and use a sharp pencil or fine-tip pen for crisp lines.
