Why we'd keep it sealed

The cards inside are worth €31 after selling costs. The box costs €263.

On average you lose €232 per box. Buying the singles you want is cheaper.

Pull rates are still uncertain. The real value could be anywhere from €26 to €42.

If you opened 100 boxes

  • 0 make money
  • 100 lose money

A typical box is worth €24. 1 in 10 boxes is worth €59 or more, and 1 in 10 is worth €13 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.
