Sustainability is of great importance, so every single CSOLLAK product is made of vegetable-tanned full grain cow leather, making them last a lifetime. I believe in traditional leather making techniques, fashioned and harmonized to the modern day consumer. My bags are entirely hand-cut and hand-sewn with true dedication and care. WE WANT TO DO MORE THAN DESIGN AND SELL BAGS, WE WANT TO DESIGN A SOCIETY WE CAN BELIEVE IN.
