Built for practical document binding

The black plastic finish gives bound documents a clean and professional appearance. It works well with a wide range of cover colours and document designs. The flexible spiral construction also makes pages easy to turn during reading, reviewing, or presentations. This combination of appearance and flexibility makes plastic coils suitable for both everyday documents and more frequently used materials.

Multiple sizes for different documents

Document thickness varies depending on the paper stock and number of pages. These coils are available from 6mm through 32mm to accommodate a broad range of binding requirements. Smaller diameters suit thinner reports and booklets, while larger coils provide more room for manuals and thicker documents. Selecting the appropriate diameter helps pages turn smoothly without putting excessive pressure on the binding.
