Thread and cord are the foundation of any strung jewelry piece. The wrong cord can lead to broken strands, loose knots, and customer returns. The right cord holds everything together securely while remaining invisible to the wearer. Nihaojewelry offers elastic cord for stretch bracelets, silk thread for classic stringing, nylon cord for strength, and leather cord for natural texture. Our cords are available on spools for custom cutting or in pre-cut lengths for consistent sizing. Diameter is consistent across batches, so production runs go smoothly without unexpected variations. Each SKU includes weight recommendations to help retailers match cord strength to bead weight. For retailers, thread and cord are a low-cost category with high impact on finished quality. Sample packs are available for retailers developing new jewelry lines.
