Authenticity — OOSYY

A process built
on zero compromise.

Before any item is listed on OOSYY, it goes through a strict four-step authentication process. We do not list first and verify later. Every piece is confirmed genuine before it reaches our store.

01 — Source

Direct Sourcing

We source exclusively from authorised retailers, brand boutiques and a verified network of luxury resellers. We never purchase from unknown or grey-market channels.

02 — Document

Documentation

All items arrive with original receipts, brand certificates, tags and packaging where applicable. Serial numbers and date codes are cross-referenced against brand records.

03 — Inspect

Physical Inspection

Our team examines stitching, hardware, labels, logo placement, material quality and finishing against brand-specific checklists built from years of hands-on experience.

04 — Certify

Certified & Listed

Only once an item passes every step is it approved and listed on OOSYY. It then ships to you securely packaged, exactly as we received and verified it.

Nothing
is overlooked.

Every product category carries its own unique authenticity markers. We know what to look for — and we look for everything.

Labels & Tags

Font, spacing, colour and stitching of all interior and exterior labels. Every detail follows brand-specific standards — any deviation is a red flag we catch.

Hardware

Weight, finish, engraving depth and logo stamp of zippers, clasps, chains and buckles. Authentic luxury hardware has a specific quality that cannot be replicated at cost.

Stitching

Stitch count per inch, thread colour consistency, seam alignment and interior lining quality. Each brand has a construction signature we verify against precisely.

Serial Numbers

Where brands use serial numbers, date stamps or authenticity cards, we verify formatting is correct and consistent with the item's production period and collection.

Materials

Texture, weight, drape and grain of leathers, fabrics and materials. Authentic pieces use specific material grades confirmed through hands-on inspection.

Packaging

Dust bags, boxes, tissue paper and authenticity cards are inspected for print quality, materials and correct brand formatting — right down to the typeface.
