THE ONE&DUNN AUTHENTICATION STANDARD
Every bag that enters our collection undergoes rigorous authentication. We do not take shortcuts. We do not rely on gut feelings. We verify, inspect, and authenticate with precision because your investment deserves nothing less.
OUR MULTI-POINT AUTHENTICATION PROCESS
Each bag is examined through a comprehensive six-step verification system designed to catch even the most sophisticated counterfeits.
Serial Number Verification
We cross-reference serial numbers with brand databases and historical records. Every number is checked for authenticity, format consistency, and alignment with the bag's production year and model.
Hardware Inspection
Zippers, clasps, buckles, and logos are examined under magnification. We verify weight, engraving depth, finish quality, and brand-specific hardware signatures that counterfeiters often miss.
Stitching Analysis
Authentic luxury bags feature precise, consistent stitching. We analyze stitch count, thread type, tension, and pattern alignment. Irregularities are immediate red flags.
Material Verification
Leather grain, canvas texture, lining quality, and material weight are assessed. We verify that materials match the brand's standards for that specific model and era.
Construction Review
We examine interior construction, pocket placement, lining attachment, and structural integrity. Authentic bags follow precise construction blueprints that fakes rarely replicate correctly.
Third-Party Authentication
For high-value pieces, we engage certified third-party authenticators to provide an additional layer of verification. Your investment is protected by multiple expert opinions.
BRAND-SPECIFIC EXPERTISE
We specialize in the most counterfeited luxury brands and know their authentication markers inside and out.
