The SEKUREX Standard
Six commitments behind every listing. Each one is something you can check for yourself.
Verified in-house inventory
Everything ships from our own stock in Woodbridge, New Jersey. No dropshipping, no middlemen, no overseas transit.
Checked before it's listed
Every listing is tested, inspected or examined as the item demands before it goes up. If it doesn't pass, it doesn't ship.
Exact-item photography
No stock images. One-of-a-kind pieces are photographed individually, and what you see in the listing is what ships.
Genuine, as listed
Maker, edition, model or specification is exactly what the listing states, named in the item specifics so you can verify it yourself.
Tracked 2–4 day delivery
Every order ships tracked from New Jersey, typically 2–4 days in the US — 0% late shipments and 100% on-time validated tracking on eBay's seller evaluation. Many listings ship free; the exact rate is on each listing.
30-day returns, every listing
Return any item within 30 days, opened straight from your eBay order. Every order is covered by the eBay Money Back Guarantee — and our transaction defect rate on eBay's seller evaluation is 0%.

Zero late shipments. Zero returns. Zero disputes. On eBay's own seller evaluation our late-shipment rate is 0%, tracking is uploaded on time and validated 100% of the time, the transaction defect rate is 0.00%, and no case has ever closed without our resolution. Orders reach the carrier in under a day on average, and when you message us a person answers — the median first reply is 17 minutes. Here's what else you can check for yourself: real inventory sitting in New Jersey, 30-day returns on every listing, and the exact item in every photograph. eBay's Money Back Guarantee covers you either way.
What we carry will grow. The standard will not — we describe what we actually hold, photograph the exact item, and let eBay hold the money until you have it. Anything we cannot carry that way, we do not carry.
What we hold right now

Frequently asked
What does SEKUREX actually sell?
Premium goods we would keep ourselves, curated across categories and held in our own stock. Right now, three things. Blank NFC hardware — NTAG424 DNA and NTAG215 cards and on-metal tags, unlocked and unconfigured, with an optional custom encoding service. Raw ungraded sports cards — rookie-year singles photographed exactly as they are, with no assigned grade. And one historic medal cover set — Fleetwood’s 1977 Spirit of ’76, serial-numbered with its original certificate; when it sells, it comes down.
Why do you sell through eBay instead of your own checkout?
Buyer protection. Every order goes through eBay checkout, so you pay with PayPal, card, Apple Pay or Google Pay, and the eBay Money Back Guarantee covers the whole transaction. We never see or store your payment details — this site doesn't take payment at all.

Where do you ship from, and do you ship internationally?
