It is estimated in wikipedia that Portugal produces approximately 50% of cork harvested annually worldwide. They are famous for being used for bottle stoppers, especially wine bottles.

Nowadays, you can find hats, bags, shoes, etc made of this lovely material.
I had this crazy idea on creating a book using this material. Therefore, I worked my mind on deciding the design and there it is....and with its own bookmark!
This book is different from the rest of the books and journals because it is like a box with the book inside.
Besides, there is a ribbon for secure closure.
I have so enjoyed working on this new item.
