eco book / book cover

Eco-friendly is minimizing energy consumption and waste.
For a minimum use of resource usage and process, "low-usage" is more ideal than "recycling" and "re-usage".

Ecobook allows the low-usage of shopping bags needed when purchasing books.
As the book itself works as a shopping bag, we do not need to make additional shopping bag to carry the book. It means any extra resource or process is not required.
