Ruler set Milan Flex & Resistant Acid 4 pcs — Protractor, Ruler, Triangle, Yellow

The Milan Flex & Resistant Acid 4-piece ruler set — Protractor, Ruler, Triangle, Yellow is a compact measuring and drawing kit designed for geometry, technical drawing and everyday school or office use. The set contains a 30 cm straight ruler, two set squares (one 90°/45°/45° and one 90°/60°/30°) and a 10 cm 180° protractor. All pieces are translucent yellow, lightweight and produced from a flexible, acid-resistant material that balances bendability with dimensional stability for repeated use.

Advantages

The components provide clear graduations and angle markings for accurate measurements and simple reading. Flexibility reduces the risk of permanent breakage and makes the tools easier to store in a pencil case or bag. Acid-resistant material ensures the set resists yellowing and degradation over time when used with typical inks and erasers. The translucent colour improves visibility of drawn lines and underlying surfaces while maintaining a consistent reference during marking.

Suitable for

• School geometry classes and homework
• Technical drawing and drafting tasks
• Architecture and design sketching
• Office tasks requiring angle and length measurement
• Hobbyist and craft projects that need precise straight lines and angles

Key specifications

• Set contents: 30 cm straight ruler, 90°/45°/45° set square, 90°/60°/30° set square, 10 cm 180° protractor
• Colour: translucent yellow
• Material properties: flexible and acid-resistant plastic
• Weight: approximately 108 g for the blister-packed kit
• Graduations and angle markings: metric measurements and degree scales

How to use

Place the chosen ruler or set square on the drawing surface and align its edge with the points you want to connect. Use the 30 cm straight ruler for long, straight lines, and the set squares to draw perpendicular or standard angled lines (45°, 30°, 60°). Position the 10 cm protractor with its baseline along the segment or vertex, then read the degrees from the marked scale and mark the required angle before drawing. For tracing curves or transferring lines, gently flex the pieces as needed without forcing sharp folds. Clean with a soft cloth to remove pencil or ink residue.

Usage recommendations

Store the set flat or in a pencil case to avoid excessive bending. Avoid exposure to high heat or strong solvents to maintain flexibility and resistance to discoloration. For precise technical work, place the tool firmly against the surface and use a sharp pencil or fine pen for clearer lines.
