The highly anticipated A5【Size】 Book Cover has finally arrived!!
This is a book cover that protects your precious books from dirt and elevates your reading experience.
It can be used not only as a book cover but also as a cover for compact notebooks and planners.
Since it comes with a bookmark, it is also recommended for those who "don't read paper books much but do use planners."
When you open your planner, notebook, or memo pad, do you sometimes forget which page you last opened? That’s when the bookmark comes in handy.
The bookmark is also very useful when inserting into books other than new ones.
Carefully selected environmentally friendly genuine materials
“We want you to use it for a long time.
”With that in mind, we paid particular attention to the choice of materials.
We adopted full-grain shrink leather tanned with plant tannins, which is highly durable.
In Bangladesh, during the Eid festival, beef is enjoyed.
Since we use the tanned cowhide after the meat is eaten, it is very environmentally friendly.
Because it is not chrome-tanned using chemicals, there is no worry about environmental pollution.
While sheep leather or synthetic leather that easily gets scratched require frequent maintenance, the properties of shrink leather mean it hardly changes over time, making it a product that can be loved for a long time in business scenes and beyond.
What is BLUE SINCERE?
“With the development of the brand, we aim to solve social issues in Bangladesh,” a philosophy we uphold,
producing bags and wallets in our own factory with Bangladeshi artisans, exploring the potential of local materials, and creating high-functionality products that are recognized even in developed countries.
