## Long description

Tetis 30 cm aluminium blue ruler is a compact straightedge made from lightweight aluminium with a 30 cm measuring length. It offers a rigid, durable edge for precise drawing, measuring and guiding cuts or layouts. The blue finish improves visibility of the scale and the slim profile makes it convenient to carry in a pencil case, folder or toolbox for school, office, drafting and general DIY use.
Advantages
The aluminium construction provides a stable, warp-resistant edge that maintains straightness over time while remaining light to handle. The printed scale along the length delivers clear graduations for accurate measurements in everyday tasks. Its compact 30 cm size balances portability and useful measuring length, and the coloured finish reduces glare and improves contrast against paper or other materials.
Suitable for
School geometry, classroom drawing and student assignments
Office measuring, layout marking and document work
Drafting, technical sketches and basic architectural layouts
DIY tasks that require a short, rigid straightedge for marking or guiding cuts
Key specifications
Material: lightweight aluminium
Length: 30 cm measuring edge
Finish: blue coloured surface for improved scale contrast
Edge type: rigid straightedge suitable for drawing and guiding cuts

How to use
Place the ruler with its flat edge against the work surface or paper, align the zero mark with the starting point, and read off the required measurement at the other end. Use the straight edge as a guide for a pencil or cutting tool, keeping steady pressure to prevent slipping. When measuring curved or uneven surfaces, ensure the ruler is properly seated along the length you wish to measure for an accurate result.
Usage recommendations
Store the ruler flat or in a protective sleeve to prevent bending and avoid exposure to corrosive chemicals or prolonged moisture. For precise cutting tasks, pair the ruler with a sharp cutter and a non-slip mat to improve safety and accuracy.
