Each piece includes an NFC chip and an official tamper-proof OKTAGON MMA hologram with a unique serial number, and is shipped with a Certificate of Authenticity. Gloves, tapes and signed jerseys come professionally framed; gloves and tapes in a black frame with a black background. Acrylic blocks hold a fragment of the original canvas, sealed in acrylic.

Enter the serial number printed on the hologram on our Verify page. You'll see the item's verification profile: its name, photos, the date it was signed (if applicable) and information about the related event or fighter. The NFC chip on the piece also leads to the Verify page. Pieces sold before 16 June 2025 have no hologram or chip.

Every autograph is 100% authentic and obtained under the direct supervision of the OKTAGON MMA team. We collect autographs only at official signing sessions, private fighter signings arranged by our Memorabilia team, and media and promotional appearances monitored by OKTAGON MMA. We guarantee the authenticity of every autograph on our collectibles.

Fight-worn gloves and tapes, and walkout jerseys, are the originals the fighter wore on fight night, straight from the cage, so they show signs of use. Wear that matches a piece's previous use is not a defect, and neither are minor cosmetic marks such as scratches or scuffs, which are common on hand-signed or used items. Pieces marked “1 of 1” are unique: only one exists.

Framed gloves and tapes measure 40x50 cm, framed signed jerseys 67x97 cm and acrylic blocks 80 mm x 160 mm. Posters come in A2 or A3. Each piece's size is in its details. Please never try to remove the hologram: it is designed to be irreversibly damaged if anyone tries to peel it off, and it can't be applied again. Keep your piece out of direct sunlight and damp.

Framed pieces are framed before they ship: framing takes 3 weeks for gloves and tapes, and 3 to 4 weeks for signed jerseys. Acrylic blocks take 2 weeks to make. Signed posters aren't framed, so there's no framing time. Each piece's description states its time. After that, delivery time depends on your chosen shipping option (see our FAQ). If the date moves, we'll let you know without delay.

Yes. Like our other products, you can return it within 30 days of receiving it through our Returns Portal, even if it is one of a kind. Pieces made to your wishes, such as a floor with your name, can't be returned. Please send the piece back as you received it, with its certificate and the hologram intact.
