CardKai

the curation

At CardKai, every card earns its place. We curate graded Pokémon, One Piece and Dragon Ball cards — PSA, CGC and ACE slabs — alongside premium raw singles, from modern chase alt-arts to vintage grails. No filler, no marketplace roulette. Every slab is hand-picked for scarcity, condition and demand, and photographed as the exact card you'll receive. This is a gallery for serious collectors across Ireland, the UK and Europe.

verify then trust

True value is value you can verify. Every graded card we sell is independently authenticated by PSA, CGC, ACE, BGS or SGC, sealed, and listed with a certification number you can check yourself before you buy. No fakes, no guesswork — a problem that plagues marketplaces like Vinted and eBay. At CardKai, authentication isn't a promise; it's printed on the slab and backed by our money-back guarantee.

we collect too

We're not a faceless marketplace — we're collectors who know the hobby. CardKai pairs a curated, premium catalogue with real expertise: live pricing insight, condition you can trust, and fully insured, tracked shipping across Europe with no customs surprises within the EU. We buy and consign too, so whether you're building a collection, chasing an investment-grade grail, or selling one, you're dealing with people who speak the language — Japanese imports, alt-arts, PSA 10s and all.
