Men’s Black Stainless Steel 5mm Byzantine Chain Necklace

SSN-179 is listed as a black-tone stainless steel byzantine chain necklace for wholesale and private-label jewelry collections. The product name describes a 5mm byzantine chain reference style; any nominal width in the listing must be checked against an approved physical sample or technical drawing, not treated as an independently verified measurement. Buyers should confirm link geometry, chain length, clasp type, finishing method, color and packaging before production. This reference chain is not presented with a verified gemstone specification, and no stone setting is presumed. Logo marking or other changes may be reviewed for feasibility. Submit expected quantity, artwork, destination market and packaging requirements for a product-specific OEM/ODM quotation. Minimum order quantity, sample timing and production lead time are agreed after technical review. Specific alloy grade, PVD process, coating durability and SKU-level REACH or laboratory test results are not claimed without supporting documentation.
