How to use

Prepare your document pages and cover sheets, align them and punch holes using a comb-compatible punching machine matched to A4 format. Open the comb of the binding machine, insert the 22 mm spine teeth through the punched holes, and release the comb to close the spine. Check alignment and rotate pages to ensure free turning. For thicker documents, confirm the page count before selecting this 22 mm spine to avoid overfilling.

Usage recommendations

For best results, use with covers or cardstock to protect the first and last pages; avoid exceeding the recommended sheet capacity to preserve spine shape and ensure smooth page turning. Store spines flat in a dry environment away from direct sunlight to prevent warping.
