How to use

Prepare your document by aligning pages and covers, then punch holes with a compatible comb binding machine according to the A4 format. Open the comb spine using the machine’s comb opener or by hand, insert the punched pages onto the comb teeth, and close the comb to secure the document. To edit the document, reopen the comb, add or remove pages as needed, and close it again. Ensure the comb is fully closed so pages are held securely and can turn freely.

Usage recommendations

For best results, use with A4-size covers and card-stock front and back protectors to improve document durability and presentation. Verify that the comb binding machine is set for 14 mm combs and check sheet alignment before closing the spine to avoid uneven binding. Store unused spines flat and protected from heat or direct sunlight to maintain shape.
