Product Description
Professional Hardware for Document Binding: Munhwa One-Touch Spring Mechanism
The Munhwa F130-2 is a premium replacement hardware set designed for spring files and DIY binding projects. Each pack contains 25 sets of high-elasticity silver metal springs and matching plastic top-locking rings. Featuring a new integrated binding system, this mechanism allows you to secure both small and large document volumes (up to 150 pages) with ease. The specialized top-locking ring ensures that even when flipping through a full load of papers, they remain perfectly aligned without slipping or detaching from the spine.
- Advanced Binding System: The innovative combination of a high-tension metal spring and a plastic top-ring provides superior security compared to traditional clips.
- Stable Document Browsing: Once the top-locking ring is engaged, pages can be turned like a book without the risk of documents scattering or falling out, even at maximum capacity.
- Rust-Resistant Silver Finish: The 70mm metal springs are specially plated in silver to prevent corrosion and maintain a smooth, professional appearance over time.
- High-Capacity Hardware: Each set is engineered to hold up to 150 sheets of paper, making it ideal for standard office reports and government archival files.
- Value Pack (25 Sets): A bulk pack of 25 complete sets (Spring + Locking Ring), perfect for office supply maintenance or large-scale document production.
