At TCGuardian, we saw sellers overpaying for bulky protectors that bend, jam USPS machines, and cost more to ship than the cards themselves. So we built something better—designed for real-world shipping, not outdated assumptions.

Before launch, we tested materials, refined sealing formats, and worked closely with manufacturing partners to improve every detail—from packaging flow to durability under pressure.

TCGuardian wasn’t built in a boardroom.

It was built by solving real problems—at seller speed.
