100 spirali per rilegatura a filo LMG bianco per 50 fogli (34RM79-WS)

Loose pages can make reports look unprofessional and are easily lost. These white wire binding spines solve that by securely holding up to 50 sheets in a clean, professional twin-loop binding. Ideal for offices, schools, and print shops, they give documents a polished, book-like finish that lies flat when open.

Who is it for

Perfect for anyone who needs to bind presentations, proposals, manuals, or reports. Whether you are a small business owner, teacher, or home office user, these spines work with any standard 3:1 pitch wire binding machine. The A4 size fits most European documents, and the 34 loops provide even pressure for a secure bind.

Tips

For best results, use a wire binding machine with a 3:1 pitch die. After inserting the spine through the punched holes, close it with the machine's crimper to secure the pages. These spines are not reusable once crimped, so plan your binding order carefully. Store unused spines in a dry place to prevent rust.
