A shoulder bag made from a combination of leather materials, featuring seal skin (fur seal), a high-grade leather, as the main material, and domestically produced steer leather at the bottom, which offers moderate softness and thickness as well as excellent durability. The strap chain design enhances the luxurious feel, taking advantage of the leather's texture. Each chain is hand-woven with leather, adding originality to the presentation of the leather and metal fittings, while also strengthening the chain, balancing both design and functionality. By using fur seal leather, known for its soft texture, for most of the bag, it becomes a bag that is comfortable and familiar to use. The main body and strap are connected with original snap hooks that can be detached from both sides. On one side, a ring is attached to allow for strap length adjustment by passing the snap hook through a round ring and folding it back to secure it. Inside, there is a zippered inner pocket on the back. This bag is meticulously crafted with a simple design that emphasizes the leather materials and embellishments. Among the marine mammals known as pinnipeds, we use particularly high-quality fur seal leather (FUR SEAL). It is characterized by its thickness, elasticity, and high strength, and is also relatively specialized in water resistance. The deep grain with its unique expression is unlike anything found in cowhide or horsehide. Being a marine creature, the leather is very resistant to surface dryness, giving it an easy-to-handle impression, and it has a smooth, fine, and soft texture, similar to kip leather.
