Common Questions

Are the slabs actually graded?
Yes — every slab is PSA, CGC, or BGS certified. We never sell raw cards in mystery slab orders. You can verify the certificate number on the grading company's website.
Can I choose the card?
No — Mystery Slabs are blind. Our team selects based on your chosen tier. If you want a specific card, browse our shop or contact us for a custom order.
What if the slab arrives damaged?
We photograph every slab before shipping and insure all orders. If your slab arrives damaged, we'll replace it or refund you — no questions asked.
How does event credit work?
Event credit is earned by joining live breaks, membership perks, and promotions. It applies a discount to Mystery Slab orders — you pay less than the listed cash price.
How fast does it ship?
Orders are fulfilled promptly and ship with full tracking and insurance. You'll receive a tracking number by email as soon as your order ships.
Can I resell my slab?
Absolutely — PSA and CGC certified cards are some of the most liquid collectibles in the hobby. Many collectors buy Mystery Slabs specifically to flip at a profit.
