When sourcing jewelry boxes, the choice of material directly impacts perceived value and protection. For the outer shell, options include MDF (Medium Density Fiberboard) for stability, solid wood for luxury, or high-quality cardboard for cost-effective eco-friendly solutions. The interior lining is critical; ensure the use of anti-tarnish velvet, microfiber, or suede to prevent chemical reactions with metals. For high-end markets, prioritize PU leather with a thickness of 1.2mm or above to ensure durability and a premium tactile feel.
