Munhwa Professional Hardboard 3-Ring D-Ring Binder B849A-71 | 2-Inch (7.5cm) | Black PP | Metal Slide Rail & Finger Ring | Made in Korea
Product Description
Engineered for High-Capacity Archiving: Heavy-Duty 2-Inch Hardboard Binder
The Munhwa B849A-71 is a high-performance, extra-capacity office binder constructed by bonding premium Polypropylene (PP) to a rigid hardboard core for maximum structural integrity. Designed to handle massive document volumes, this professional model features metal "Slide Rails" on the bottom corners to protect against shelf friction and a reinforced "Finger Ring" on the spine for effortless retrieval. Equipped with a robust 2-inch D-ring and a transparent pocket index system, it provides the ultimate organized solution for managing large-scale corporate records.
- Heavy-Duty PP-Hardboard Build: The powerful adhesion between the hardboard and PP material prevents warping and protects contents from external impact even at full capacity.
- Protective Metal Slide Rails: Features extended metal rails on the base edges to eliminate wear and tear caused by frequent sliding on office shelves or cabinets.
- Reinforced Spine Finger Ring: Includes a chrome-plated steel finger ring that resists rust and discoloration, making it easy to pull heavy, full binders from tight spaces.
- 2-Inch High Capacity: The 75mm spine and industrial-grade D-ring mechanism securely accommodate up to 400 sheets of A4 paper.
- Multi-Sided Pocket Index: A high-transparency spine pocket with a 3-sided index card provides ample space for detailed titling and efficient categorization of large archives.
