Plastic flexible ruler Centrum 15 cm model 86638

Flexible 15 cm plastic ruler by Centrum model 86638 is a compact measuring tool designed for everyday use in school, office and craft activities. The ruler is made of bendable plastic that resists snapping and adapts to slightly curved surfaces while keeping clear metric graduations up to 15 cm for precise measurements. Its slim profile and moderate stiffness make it convenient to carry in a pencil case or workplace drawer and use for drawing straight lines, measuring short distances and marking materials for cutting or folding.

Advantages

The flexible construction reduces the risk of breakage compared with rigid rulers and allows the tool to follow curved edges without losing scale accuracy. Metric graduations are clearly printed for easy reading. Lightweight and compact, the ruler is simple to store and transport. Its material provides a balance between flexibility and stability, enabling both precise linear measurements and minor shaping tasks on thin or slightly curved surfaces.

Suitable for

• Schoolwork and classroom exercises for primary and secondary students
• Drawing and drafting basic diagrams or straight lines
• Hobby and craft projects such as scrapbooking, model making and paper folding
• Everyday office tasks like measuring small items and marking documents
• Designers or illustrators needing a portable guide for short straight segments

Key specifications

• Length: 15 cm
• Measurement system: Metric (centimetres and millimetres)
• Material: Flexible plastic
• Transparency: Semi-transparent to allow alignment of markings
• Edge type: Straight measurement edge suitable for drawing and marking

How to use

Place the ruler on the work surface with the printed graduations aligned to the start point of the measurement. For measuring along flat surfaces, press the ruler gently to keep it steady and read the required value at the mark. To follow a curved edge, bend the ruler along the contour while ensuring the zero mark remains at the reference point; read the measurement at the target location. Use the straight edge as a guide for drawing lines with a pencil or pen, keeping a consistent light pressure to avoid slipping. After use, store the ruler flat or rolled gently to maintain its shape and accuracy.

Usage recommendations

Store the flexible ruler away from heat sources and sharp objects to prevent deformation or cuts. Clean with a soft cloth and mild soapy water if needed, and avoid strong solvents that may damage printed graduations.
