Why You'll Love This Ruler

• High-Precision Laser-Etched Scales: Engraved directly into the solid aluminum alloy body, the markings are wear-resistant and fade-free, delivering clear, accurate readings for every measurement, drafting, and cutting task.
• Raised Safety Guard Edge: A thickened raised aluminum guard channel along the cutting edge keeps utility knife blades on track and away from your fingers, greatly improving safe cutting for users of all ages.
• Non-Slip Textured Base: Integrated anti-slip texture on the underside holds the ruler firmly in place on your work surface, ensuring perfectly straight lines and clean cutting edges every time.
• Ink Bleed Resistant Surface: The smooth anodized aluminum surface prevents ink from seeping into the ruler body — wipe off stains effortlessly and keep scales clear for long-term use.
• Superior Long-Term Durability: High-strength aluminum alloy resists bending, rust, and impact far longer than plastic alternatives, even under heavy, repeated use.
• Three Size Options: Choose from 20 cm, 30 cm, or 45 cm to match your specific project needs — classroom lessons, scrapbooking, architectural drawing, or professional craft cutting.

Frequently Asked Questions

Q: What sizes does the aluminum alloy ruler come in?

A: The ruler is available in three sizes: 20 cm, 30 cm, and 45 cm. Each size is made from the same high-quality aluminum alloy, so you can choose the length that best suits your measuring or cutting project.

Q: How does the raised guard edge protect me during cutting?

A: The thickened raised aluminum alloy guard edge runs along the cutting side of the ruler, creating a physical channel that guides your utility knife blade and prevents it from riding up over the edge toward your hand, making cuts safer for both adults and students.

Q: Will ink from markers or pens stain the ruler permanently?

A: No. The smooth anodized surface of the ruler resists ink absorption, so any ink marks or stains can simply be wiped away with a damp cloth, keeping the scale markings crisp and legible over time.

Q: Is this ruler suitable for classroom and student use?

A: Absolutely. The combination of laser-etched precise scales, non-slip base, and raised safety guard makes this ruler an excellent tool for teachers and students alike — ideal for measuring, drafting, and guided craft cutting in classroom settings.
