Pure Copper Silver-Plated 925 Best Quality Version, Crocodile Heart, Removable Style. The chunky, rugged design features a large tongue made of pure copper, silver-plated in 925. During production, the black oxidation of the 925 silver is intentionally retained, followed by polishing to create a shiny silver surface with soft gray and black shadows, resulting in a very pronounced sense of layering. The strap is made of imported crocodile-embossed cowhide, blending elements of rock punk, gothic, and street hip-hop, with a unique design style that exudes an air of mystery and luxury. Width: 3.8 cm.
