Hardware is often the first point of failure. Ensure all metal components (clasps, zippers, and chains) are made of electroplated zinc alloy or stainless steel to prevent rusting and color fading. Request salt spray test reports to confirm corrosion resistance. In terms of craftsmanship, check for uniform stitching (at least 7-9 stitches per inch), the absence of loose threads, and smooth zipper operation. For embellished clutches, verify that beads, crystals, or sequins are hand-sewn rather than just glued, as adhesives can fail in high temperatures during transit.
