Signed Kits is a Standard-tier Dutch authenticator of signed football shirts, founded by Kaan Kelezoglu and registered in the Netherlands (KvK 91401097). It establishes provenance by running its own signing sessions and recording them, so an autograph's origin is captured as it is given rather than judged afterwards.
How Signed Kits authenticates
It authenticates by witnessing the signing itself: Signed Kits organises its own sessions with players and records them on video, capturing the autograph as it is given rather than forming an opinion about it afterwards. Each item is issued a Certificate of Authenticity, with the session footage as its backing evidence. The business is founded and run by Kaan Kelezoglu and registered in the Netherlands as KvK 91401097.
What you receive and how to verify it
The proof is the signing on video: a signed shirt comes with a Certificate of Authenticity and video evidence of the session in which it was signed, so a collector can watch the autograph being given rather than relying on the seller's word. Signed Kits does not run a public certificate-lookup portal; the session video and the COA are the verification.
Why this matters for collectors
For a collector, Signed Kits' value is signed-at-source Dutch provenance with video proof: the autograph is captured at the moment of signing, the right assurance for items from its own sessions. Walkouts references Signed Kits where that session-witnessed, video-backed provenance is the right fit, alongside the premium bureaus it uses first for high-value pieces.
