The rush of the rip — with real, graded Pokémon cards inside. Tap open and watch the reveal live. Every DOPA! mystery pack could be hiding a genuine, graded card — yes, PSA 10s included — shipping straight to your door. And here's what makes DOPA! different: any card you don't want converts back to 100% of its market value in credit, so every pull moves you closer to the one you really want. No hidden odds, either — every pack shows its chances up front, and every card is 100% authentic. That's why DOPA! is Japan's #1 oripa app, rated 4.9/5 by 100,000+ players worldwide — with millions of cards shipped to hundreds of thousands of collectors. Fair odds. Real cards. Every pull moves you forward. Download DOPA! and open your first pack.

Measure your cards. Don't guess. Bind measures how well a trading card is centered — the left/right and top/bottom margins, to a tenth of a percent. BUILT FOR ACCURACY • A spirit level keeps the phone parallel to the card, so the shot is square. • Bind finds the card's edges for you, then you refine each corner at up to 12x. • Shot at an angle? Bind corrects the perspective mathematically, so the numbers hold even when the photo isn't perfectly flat. SEE WHAT THE NUMBERS MEAN The margin between the cut line and the print frame is shaded — the wider side fills in, so you see which way a card is off at a glance. KEEP THEM TOGETHER Every measurement lands in your Binder with its photo and outlines. Track how many of your cards fall inside the published 60/40 guideline. COMPARE WITH OTHER COLLECTORS Post a card and see where it ranks against every other copy of the same card. One reaction: Well-centered. WHAT BIND DOES NOT DO • No grade predictions. Centering is one of several things graders score; we show the measurement and the published guidelines, nothing more. • No prices, no trading, no location.
