Authenticity & Inspection
Every SAZO piece is verified through Corelytics™, a three-tier authentication framework developed by Insightview Tech (the deep-tech arm of our Korean sourcing partner, Bunjang) and presented at Pittcon 2026, one of the world’s leading conferences for analytical chemistry. Items are only listed after passing every stage below.
1. Expert Hand Inspection
Category-specific specialists (handbags, watches, jewelry) work through up to 18 inspection stages by hand — craftsmanship balance, stitching flow, hardware placement, logo execution, and structural integrity.
2. Spectroscopic Analysis
A portable instrument stack — X-ray fluorescence (XRF), near-infrared (NIR), and FT-IR spectroscopy — performs non-destructive testing on metals, leather, and hardware. The combined readings surface elemental and molecular inconsistencies invisible to the human eye.
3. AI Pattern Recognition
A deep-learning model trained on hundreds of thousands of prior inspections cross-references each item against a verified reference set, flagging subtle pattern deviations to corroborate the human and spectroscopic findings.
The Corelytics framework has reported authentication accuracy above 99.99% across 87,579 inspections in 2025 and 52,907 in 2024, as disclosed at Pittcon 2026. A final quality inspection is performed in Korea prior to every shipment, with preemptive notification to you if anything is found.
Inspected at a Luxury Showroom — Seoul, Gangnam
Items pass through a dedicated luxury showroom in Seoul’s Gangnam district, where pre-owned pieces are physically inspected, photographed, and stored prior to listing. The facility houses dedicated zones for handbags, small leather goods, jewelry, and watches — alongside one of Korea’s largest single-store Chanel bag collections and curated lineups from Hermès, Bottega Veneta, Rolex, Audemars Piguet, Patek Philippe, Cartier, and Van Cleef & Arpels.
