【 Carefully Selected, Eco-Friendly Genuine Materials 】

“We want you to use it for as long as possible.”
With this sentiment, we made no compromises in material selection and were thoroughly particular.
The material used is durable full-grain shrink leather tanned with plant tannins.
It is a sustainable material, repurposed from cowhide consumed as food during the Bangladeshi festival “Eid.”
Unlike chrome tanning, which uses many chemicals, it is finished with natural ingredients, eliminating concerns about environmental pollution.
Unlike sheep leather or synthetic leather, which can easily get scratched, shrink leather is less prone to visible scratches and is easy to maintain.
It is also resistant to significant degradation over time, making it a product for adults that can be used with confidence in business settings.
