Most bags on the market are primarily made with plastic supports, which are prone to deformation and creasing after short-term use. Additionally, plastic support structures are not environmentally friendly, as they are difficult to recycle and contribute to environmental pollution. To address these issues, we aim to use aluminum for its durability, which can extend the lifespan of bags, and its recyclability, which can reduce environmental impact. Furthermore, we believe that combining sheet metal with leather can create new market opportunities for the industry.
