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.
Why we'd keep it sealed
The cards inside are worth €28 after selling costs. The box costs €400.
On average you lose €372 per box. Buying the singles you want is cheaper.
Pull rates are still uncertain. The real value could be anywhere from €19 to €49.
