Your listing says "very good condition."
A report proves it.
An expert examines your item over video call for 45 minutes. You receive a timestamped report to attach to your listing.
Every point of the protocol receives one of three states: pass, flag, or not checked. Nothing is rounded, nothing is averaged, no overall score is calculated.

How it works
01

An expert calls you back over video and guides you, step by step.

The Dorynn app
The owner prepares their file and holds the session from the app, on their phone. Available on iOS and Android.
From €49
Paid by the seller to strengthen their listing, or by the buyer to have a far-away item checked. The price follows the item's value, never the outcome of the report.
