This is not a defect — it’s part of our intentional design.
At Zno, we apply less glue and tape at the spine to allow your book to:
- Open and close smoothly
- Lay flat without resistance
- Stretch naturally without tearing
This design ensures durability and a premium, lay-flat experience.
FAQ
Q: Will the spine come apart over time?
No. The reduced glue at the spine is engineered to enhance flexibility – not reduce strength. Your book is built to last.
