Bead caps and spacers are functional components used in jewelry making to protect main beads, conceal knots, and add visual separation between elements. Unlike decorative beads, these findings serve a structural role in finished pieces. Nihaojewelry selection includes bead caps in multiple shapes and sizes, spacers in various thicknesses, and both components across silver-tone, gold-tone, rose gold, and antique finishes. Pearl-specific styles feature matte inner walls to reduce friction. Cartoon styles for children's jewelry meet CPSIA safety standards with documentation available. All styles receive edge finishing to ensure smooth stringing and wear. Clear specifications per SKU help retailers select the right components for their specific bead types and application requirements.
