This protects the perforations in your documents, even with intensive use and frequent turning of pages.
- Maximum stability: The 4-point fastening keeps even heavy contents securely in place.
- Professional appearance: Ideal for high-quality presentation folders where dividers must fit perfectly.
- High capacity: Available in various capacities for stacks of paper ranging from a few millimetres to several centimetres.
