A "mystery box" here means one card. The mystery is which card you pull, not how many. You are buying a single pack that reveals one individual card, which then ships to you or sells back instantly. MyPrize does not sell sealed boxes, booster boxes, or Elite Trainer Boxes.
How it works
Pick a pack
Browse the packs, pick one, and buy it. Every pack holds one individual card, and that card is a real, physical collectible.
Rip it live in a shared room
Hit RIP and watch the reveal happen live, in the same rooms where streamers open theirs.
Keep the card or cash out instantly
Ship your single card to your door, or sell it back for instant value. You have three hours to decide; after that it sells back automatically.
