Certificate of Authenticity

We refuse to let knock-offs tarnish the reputation we’ve built. Every genuine Gladius comes with our Certificate of Authenticity, your guarantee that what’s in the box is the real deal.

What is Gladius Certificate of Authenticity (COA)?

The certificate is your gears' ID. It comes in the box of every purchase of an original product from Gladius. You will easily identify it to be a piece of paper stamped with a Gladius wax seal.

A confirmation your glove is an original

A real certificate of authenticity attests that the piece you have in your hands shipped straight from our warehouse and not from some fly-by-night counterfeiter.

Marked In Fire

Your Certificate of Authenticity bears the Gladius burgundy wax seal, attesting to its authenticity. A tradition that once adorned the most important documents of ancient Rome, now carried in your hands.

Why the Certificate of Authenticity matters? 

In the world of combat sports gear, counterfeit products have become a persistent issue. Whenever a brand creates something exceptional, countless imitators appear, flooding the market with replicas that attempt to mimic the original. A brief scroll through any Reddit thread is enough to see how widespread this problem has become.

FAQ Certificate of Authenticity

What exactly is the Gladius Certificate of Authenticity (COA)?

The COA is an official document included with every genuine Gladius product. It features a red wax seal, an unique serial number that encodes your gear’s model, batch, and production year, plus the founder’s handwritten signature—proving your equipment is 100% authentic.

What should I do if I lose my COA? 

Contact Gladius customer support (contact@gladiusfight.com) with your purchase details (order number, date, and seller). We’ll cross-check our records and can reissue a digital copy tied to your serial number.

Can I purchase the COA separately if I bought from a third-party seller? 

No. Certificates are only issued with new, genuine Gladius products shipped directly from us or our authorized retailers. If your gear lacks a COA it’s likely counterfeit.

Are all Gladius products covered by a COA? 

Yes. Every glove that leaves our warehouse has an unique COA.

What if my item serial number doesn't work as a discount code?

First, ensure you entered the number exactly as shown (including any leading zeros). If it still fails, reach out to support with a photo of the COA—our team will verify and reset the code if necessary.

How can I check if my COA is genuine? 

  • Wax Seal: Look for the vibrant burgundy Gladius seal.
  • Serial Number: Enter it on our website’s checkout page; it should activate your 8% lifetime discount.
  • Signature: Confirm the founder’s handwritten signature is present and unaltered.
