✔ Jewelry Sealants – E.g., ProtectaClear

6. 품질 관리 & 포장

6.1 Inspection Checklist

✔ No sharp edges (줄질 & smoothing complete)
✔ Patina consistency (No unintended blotches)
✔ Ring size accuracy (Test on mandrel)

6.2 Packaging for Retail

  • Anti-Tarnish Pouches (Prevent oxidation during storage)

  • Branded Boxes (Luxury presentation)
