Ensemble de règles Herlitz 11368222

The Herlitz 11368222 ruler set contains four measuring tools designed for everyday school and office tasks: a 30 cm straight ruler, a 10 cm protractor, and two triangles that together cover common angle and straightedge needs. The items are made of transparent coloured plastic to allow accurate alignment over drawings and text. The set is supplied in a blister pack for compact storage and easy access when preparing lessons, technical sketches or homework.

Advantages

The transparent multicolour plastic improves visibility over paper and printed materials while helping to distinguish tools quickly. The 30 cm straight ruler offers clear metric graduations for precise linear measurement. Two triangles provide fixed angle references for drawing and checking right angles and common slope lines. The protractor includes degree markings for measuring and constructing angles. The blister packaging keeps the set together and protects the edges of the instruments during storage and transport.

Suitable for

• School geometry exercises and general classroom use
• Technical drawing, sketching and layout work
• Home homework and craft projects that require accurate measuring
• Office tasks such as quick measurements and layout checks

Key specifications

• Contents: 30 cm straight ruler, 10 cm protractor, two triangles
• Material: transparent coloured plastic
• Graduation: metric markings on ruler and protractor degrees
• Packaging: blister pack for storage and protection

How to use

Select the appropriate tool for the task: use the 30 cm ruler for straight lines and linear measurement, the triangles for drawing perpendiculars and common angles, and the protractor for measuring or constructing angles. Place the transparent tool over the drawing so the markings align with the reference points on the paper. For greater accuracy, keep the instrument flush against the surface and use a sharp pencil or fine-tipped pen for marking. After use, return the pieces to the blister pack to avoid loss or damage.

Recommendations

Store the set flat and avoid exposure to high heat to prevent warping. Clean with a soft cloth and avoid abrasive cleaners to preserve the clarity of the transparent plastic and the legibility of the printed graduations.
