Five Metals, One Craft.

BISSZA is a brand under INUNION, it’s a leather goods hardware brand built on five key materials: Brass, Iron, Stainless Steel, Zamak, and Aluminium. The name BISSZA comes from the first letters of these five materials.

Each material has its own role. Brass brings warmth and a classic feel. Iron gives strength. Stainless Steel offers clean looks and lasting use. Zamak makes detailed shapes possible. Aluminium adds lightness and balance.

Together, they form the base of BISSZA.

We focus on metal accessories for leather goods, including chains, buckles, rings, hooks, tags, and custom metal parts. Every piece is made to work well, look good, and fit naturally with the leather product.

For us, hardware is not just an accessory. It is part of the design, part of the function, and part of the product’s final character.

Five metals. One craft.
This is BISSZA.
