Authentication & Authenticity Guarantee
All products on Vierlot are strictly verified via standardized multi-layer authentication, in official partnership with LegitApp and Entrupy. Every order comes with physical security tags, official digital certificates and comprehensive after-sales protection, so you can shop with full confidence.

Official Partnership with LegitApp & Entrupy
Vierlot maintains official partnerships with LegitApp and Entrupy, two globally recognized leaders in luxury authentication.
LegitApp provides AI-powered verification and tamper-proof QR tags for all our products, ensuring full traceability.
Entrupy offers patented microscopic authentication for eligible handbags, delivering lab-grade results accepted by platforms and buyers worldwide.
For customers seeking additional domestic verification support, we also collaborate with CCIC (China Certification & Inspection Group), a leading inspection body in China.
Standard Manual Appraisal Process
We follow a strict 3-step appraisal procedure for every product:
- Full Craft Inspection: Verify leather, hardware, logo, stitching, lining and all original details.
- Condition Recording: Document wear and flaws truthfully without any concealment.
- Final Double Check: Reconfirmed by senior experts to screen out non-conforming goods.
We never sell refurbished, spliced, altered or counterfeit luxury products.
Tamper-Evident Protection
Every authenticated genuine item is sealed with a unique Vierlot Tamper-Evident Seal before delivery.
An intact seal proves the item has not been replaced or tampered with during transit.
Removing, cutting or damaging the seal voids all condition-discrepancy claims and the expedited 30-day re-verification support. Authenticity claims remain protected under our Sovereign Lifetime Authenticity Guarantee, subject to formal laboratory verification and custody matching.
If the seal is broken or missing upon delivery, please contact us immediately and do not accept the item if possible. We will assist with inspection and resolution.
After-Sales Guarantee & Global Re-Authentication
Sovereign Lifetime Authenticity Guarantee
At Vierlot, our authenticity commitment is permanent and irrevocable. Every creation sold is backed by our Sovereign Lifetime Authenticity Guarantee for the physical core body of the piece.
If an item is independently confirmed counterfeit by an accredited, globally recognized luxury authentication authority (including, but not limited to, LegitApp, Entrupy, CCIC, or equivalent credentialed testing laboratories), Vierlot commits to:
- Issuing an immediate 100% full refund of the original purchase amount to your original payment method;
- Reimbursing 100% of the documented official third-party authentication inspection fees incurred by the client;
- Covering all reasonable round-trip international return shipping freight and customs clearance fees.
To ensure chain-of-custody integrity and eliminate fraudulent substitution, the item evaluated must be incontrovertibly established as the exact identical piece dispatched by Vierlot, cross-matched against our pre-shipment 4K macro inspection archive and serial records.
Global Re-Authentication Concierge
You are always welcome and encouraged to re-authenticate your acquisition via any accredited, internationally credentialed channels (such as LegitApp, Entrupy, or recognized independent appraisal laboratories). We will provide comprehensive archival photos and export documents to assist your verification.
- 30-Day Concierge Support Window: We recommend submitting your acquisition for third-party verification within 30 calendar days of delivery. During this period, our dedicated concierge team provides expedited priority support and claims handling, provided the Vierlot serialized tamper-evident security seal remains 100% intact and undisturbed.
- Lifetime Protection: Authenticity claims submitted beyond the 30-day window remain fully protected under our Lifetime Authenticity Guarantee, subject to formal laboratory verification and custody matching.
- Evidentiary Standards: Claims require an official, verifiable written digital or physical appraisal report featuring a legitimate registry tracking code from an accredited authority. Subjective personal opinions, non-certified commercial appraisals, normal vintage aging, or items with missing/tampered security seals are strictly excluded from coverage.
- Inspection Costs: Third-party authentication fees are initially incurred by the client. Upon official verification of any authenticity non-conformity, 100% of legitimate appraisal fees will be promptly reimbursed by Vierlot alongside your full order refund.
