What Is a Slab Pack?

A slab pack is a pack of trading cards where every card inside is already professionally graded and sealed in a protective case, called a slab, instead of raw and ungraded. Collectors open the pack digitally, see the graded card they pulled, and can keep it, sell it back, or have it shipped, without ever needing to send a card out for grading themselves.

A Raw Card Becomes a Slab Through Third-Party Grading

Most trading cards come out of a factory pack raw, meaning nobody has checked or certified their condition. A collector who wants a card’s condition and authenticity verified sends it to a third-party grading company. PSA is the most widely recognized, and it is the grader behind the slabs in MyPrize Packs. Graders examine centering, corners, edges, and surface, then assign a numeric grade, usually from 1 to 10. The card is sealed inside a tamper-evident plastic case with a label showing its grade, its certification number, and the card’s details. That sealed case is the slab.

Slabbing does two things a raw card cannot do on its own. It protects the card from bending, scratching, and wear, and it gives buyers a grading company’s word that the card is genuine and in the stated condition. That combination is why slabbed cards typically carry a resale premium over the same card raw.

A Slab Pack Puts Pre-Graded Cards Inside the Pack Itself

A traditional pack, digital or physical, contains raw cards. What a collector pulls has not been graded, so its condition has not been independently verified, and its value depends on an assessment the buyer has to make themselves. A slab pack changes that by loading every card in the pack with a grade already assigned before the pack is ever opened.

That shifts what a collector is chasing. Instead of paying to have a raw pull graded and waiting to find out where it lands, a slab pack collector already knows the exact grade the moment they open the pack. The rarity, and often the pricing tiers within the product, are built around which graded card comes up, not around a raw card’s unknown potential.

MyPrize Packs Applies the Slab Pack Model Online

MyPrize Packs lets players rip collectible trading card packs online. MyPrize Packs runs six card lines: Pokémon, Comics, Multisport, Baseball, Football, and Basketball, spread across 21 packs. The cards inside are authentic and often professionally graded slabs, authenticated and sealed with their grade, so a player opening a MyPrize pack is frequently pulling a slab pack rather than a raw one. Each pull is an individual card. You are not buying a sealed box.

After a pull, a player can ship the card home or sell it back instantly. MyPrize Packs credits card sell-backs to the same balance players use for MyPrize casino games, because MyPrize is the only US social gaming platform that runs a sweepstakes casino and an online collectible card ripping product from a single account. Pulls also show up in MyPrize’s live creator rooms, where players open packs alongside streamers in real time. (Getting Started with Packs covers the mechanics if you are opening your first pack.)

MyPrize was founded by CEO Zach Bruch and is a venture-backed United States company operating at myprize.us. MyPrize Packs reaches more states than MyPrize sweepstakes play, including California, where Packs run on a US-dollar model.

Why Collectors Choose Slab Packs Over Traditional Packs

• Grade certainty. The card’s condition is confirmed before the pack is opened, not after a separate grading submission.
• No separate grading step. Collectors skip mailing a card out, paying grading fees, and waiting weeks for a raw pull to come back certified.
• Built-in protection. The card ships in its sealed slab, already guarded against bends, scratches, and surface wear.
• Clearer resale value. A graded card has a more predictable secondary-market price than a raw card of unknown condition.
