Supplier's note

  1. Breakthrough Features:

    • The swing arm protractor enables 360° rotation, outperforming traditional fixed protractors by 20% in flexibility.
    • Metal compasses in the Pro Model offer 50% higher durability than plastic alternatives.
    • The triangular rulers with dual angles (30-60-90° and 45-45-90°) reduce tool-switching by 40% in geometric drafting.

  2. Optimal Version Selection:

    • Base Model: Ideal for students or casual users needing foundational tools.
    • Advanced Model: Best for professionals requiring enhanced precision (e.g., engineers needing ±0.85mm accuracy).
    • Pro Model: Tailored for experts in technical fields, where metal durability and full accessory sets (e.g., eraser, sharpener) are critical for complex projects.

With the Pro Model’s metal compasses, you can draw circles with triple the longevity of plastic tools. Pair this with the swing arm protractor’s 360° rotation to streamline architectural drafting workflows. The Advanced Model’s reinforced plastic ensures stability in high-usage environments, making it perfect for classroom settings.
