【 Simple × Luxury | Unisex Leather Backpack 】
This high-quality backpack features a refined design that naturally blends in for both women and men.
It has a spacious design that can comfortably store A4 size documents and a 14-inch laptop, along with a variety of pockets, while achieving a lightweight feel that is rare for cowhide.
Utilizing luxurious shrink leather made entirely from silver leather, it is resistant to scratches, water, and dirt, ensuring high durability.
The wide shoulder straps reduce the burden on the shoulders even with heavy loads.
This is a stylish item for adults that can be paired not only for commuting and school but also for casual weekend styles.
【 Carefully Selected, Eco-Friendly Genuine Materials 】
"We want you to use it for as long as possible."
With this thought in mind, we made no compromises in material selection and were thoroughly particular about it.
The material used is full-grain shrink leather tanned with plant tannins, known for its durability.
This sustainable material is made from the hides of cows consumed as food during the Bangladeshi festival "Eid," minimizing environmental impact.
Instead of using chromium tanning, which relies heavily on chemical agents, it is carefully finished with natural ingredients, thus minimizing environmental effects.
Unlike sheep leather or synthetic leather, which are prone to scratches, shrink leather is less noticeable for scratches and easy to maintain.
Furthermore, by using only 100% silver surface leather instead of cheap split leather, we achieved the high-quality texture and depth unique to genuine leather.
It is also resistant to significant deterioration over time, and its charm increases the more it is used.
This is a genuine product for adults that can be used with confidence in business settings for a long time.
