The Karbon standard

The core is the whole point.

The name isn't an accident. Genuine cards owe their feel to an opaque dark core layer — it's why you can't see through them and why they snap when you shuffle. Cheap proxies skip it and always give themselves away.

We print on true 330gsm black-core casting stock, seal it in linen-textured film, and die-cut to spec with 3mm rounded corners. The result passes the light test and sleeves like the real thing — while staying honestly, visibly a proxy.

Good to know

Questions, answered.

Are these official cards?

No — every Karbon card is a clearly-marked proxy for casual play and deck testing. They're not tournament-legal and aren't sold as authentic.

What are they made of?

330gsm German black-core stock, linen-textured lamination, 3mm rounded corners — the same materials that give real cards their feel.

Will they sleeve with my real cards?

Yes. Standard 63×88mm poker size, so they shuffle and sleeve alongside genuine cards without standing out by thickness.

Can I order specific cards or custom art?

Yes — that's what the custom order page is for. Paste any decklist, pick the printing for each card, and add it straight to your cart — priced instantly.
