Pre-Loved but Perfect: How We Authenticate Every Bag at KYM
When it comes to luxury, trust is everything.
At KYM, we understand that purchasing a pre-loved designer handbag isn’t just a transaction — it’s an investment. That’s why every item we sell undergoes a rigorous, multi-step authentication process to ensure it meets our exacting standards of quality, originality, and condition. Whether you’re eyeing a Chanel Classic Flap or a Hermès Kelly, you can shop with complete confidence.
Our Promise: 100% Authentic, Always
Unlike fast fashion, luxury bags are crafted to last a lifetime. But with the increase in counterfeit goods on the market, even seasoned collectors can struggle to spot a fake. At KYM, we take the guesswork out of second-hand shopping. Every piece in our collection is authentic, traceable, and quality-checked by experts.
Here’s how we do it.
Step 1: Sourcing From Trusted Networks
We only source from reputable sellers, collectors, and suppliers — individuals and partners who have a verified track record in luxury resale. Each piece begins its KYM journey with a full history check and preliminary inspection before it even enters our studio.
Step 2: Physical Inspection by Experts
Our in-house team includes professionals trained in luxury craftsmanship and brand-specific design standards. They examine:
-
Hardware & Stitching: From serial numbers to logo engravings, we compare every detail to verified brand guidelines.
-
Materials: We identify leather types, lining fabrics, and specialty finishes unique to luxury houses like Hermès, Dior, and Louis Vuitton.
-
Construction: The bag’s shape, seams, and structural integrity all tell a story — and our experts know exactly what to look for.

Step 3: Expert Designer Authentication Services
Investing in a pre-owned designer handbag? With so many fakes around, authenticity is key.
In addition to authenticating our own stock, KYM offers independent third-party authentication services — whether you're buying from us or elsewhere. Just send us photos, a purchase link, or visit us in-store, and we’ll verify it for you.
