BISSZA was born from a passion for metal craftsmanship and a simple question long overlooked in luxury leather goods: Why do the most refined designs often fail at the hardware—the small, critical parts that wear out, rust, or break? We believe a bag’s true lifespan and luxury feel aren’t just in the leather—they’re in the buckles, locks, and chains that hold it all together.

Founded in 2008, what began as a small team specializing in metal components has grown into a one-stop supplier trusted by 5,000+ clients across 150+ countries, from luxury European workshops to fast-fashion Asian brands. For 15+ years, we’ve navigated the changing trends of the leather goods industry—from the rise of sustainable sourcing to the demand for custom OEM/ODM solutions—while staying true to our core promise: to deliver durable, high-quality metal hardware that elevates every leather creation.

Our name, BISSZA, honors the five core metals that define our work: Brass, Iron, Stainless Steel, Zinc Alloy, and Aluminum Alloy. It is not just an acronym—it’s our promise to Build Integrity, Strength, and Sustainability into Every Metal Accessory. We combine the best of these five core metals: brass for stability, iron for strength, stainless steel for corrosion resistance, zinc alloy for precise shaping, and aluminum alloy for lightness. This isn’t just material choice—it’s professional hardware design that makes your leather products last.

BISSZA is part of the INUNION group, which manages numerous leather goods and hardware brands, floral packaging brands, as well as motorcycle accessory brands.

For 15+ years, BISSZA has been more than a supplier—we’re a partner in your brand’s success. Whether you’re a small independent designer in New York or a global fashion house in Milan, we deliver the precision, flexibility, and sustainability your leather goods need.

This isn’t just hardware—it’s the strong foundation that makes your design last. Choose BISSZA, and let our metal craftsmanship share your brand’s story.
