Rip it€105 of cards inside, after selling costs

Estimated contents: nobody has published measured pull rates for this box yet, so we use those of boxes with the same pack layout. Treat the numbers as a rough guide.

See the mathPrice history

Why we'd rip it

The cards inside are worth €105 after selling costs. The box costs €62.

Most boxes come out ahead: only 6 of 100 boxes lose money.

Pull rates are still uncertain. The real value could be anywhere from €92 to €132.

If you opened 100 boxes

  • 94 make money
  • 6 lose money

A typical box is worth €99. 1 in 10 boxes is worth €149 or more, and 1 in 10 is worth €67 or less.

The math, per box

From the price of every card to what you'd actually keep.

How we work this out

We price every card at its Cardmarket market value, take off the selling costs above, and open 100,000 virtual boxes slot by slot using the pull rates in the table. The verdict compares the cards with the box price and checks how often a box loses money.
