Material Durability | Industrial drafting, frequent use | - Industry Standard: ASTM D543 (resists 30+ chemicals) - Our Base: Durable plastic (ISO 179 impact resistance) - Our Advanced: Metal alloy (exceeds ISO 179 by 20%) | ▲ Advanced: 20% stronger than Base (ideal for harsh environments) Lightweight (30g) for all tiers | Base: Slightly less corrosion-resistant than Advanced |
Tip Precision | Technical drawings, fine art sketching | - Industry Standard: 0.5mm tip (ISO 9000) - Our Base: 0.5mm tip (meets ISO 9000) - ▲ Our Advanced: 0.3mm tip (ISO 10654) | Advanced: 40% finer lines for precision work Consistent ink flow in all tiers | Base: Limited to medium-detail work |
Weight & Portability | On-the-go use, prolonged writing | - Industry Standard: 40–50g average - Our Base/Advanced: 30g (lighter than 70% competitors) | ▲ Lightweight design reduces hand fatigue Same weight across tiers | May feel flimsy in low-quality pens (Base tier) |
Customization | Corporate gifts, personalized branding | - Industry Standard: No standardization - Our Base: Basic engraving (up to 10 characters) - ▲ Our Advanced: Full-color printing + engraving (ISO 12840) | Advanced: Customizable for corporate branding Cost-effective for bulk orders | Base: Limited customization options |
Ergonomics | Long drawing sessions | - Industry Standard: Flat grip (ISO 9241) - Our Base: Green rubberized grip (ISO 9241-compliant) - ▲ Our Advanced: Contoured grip (ISO 9241 + 30% pressure reduction) | ▲ Advanced reduces hand strain by 25% Comfortable for all tiers | Base: Less effective for users with large hands |
Versatility | Multi-purpose use (writing + drawing) | - Industry Standard: Single-purpose (drawing only) - Our Base: Dual-use (drawing/writing) - ▲ Our Advanced: Technical drafting + waterproof ink (ASTM D4236) | ▲ Advanced: Suitable for architects/engineers Base: Affordable for general use | Advanced: Higher cost compared to Base |
