It arrived!!!
It contained slibs of different hardness, which I enjoyed, thinking it was staged!
I was very disappointed that the card was transparent through the bag.
I won't reveal the contents, but it seems to be an Oripa. It's a big hit, but when it goes downhill, it's a blast. The packaging was very nice, and it came with extras that will make me buy it again next time!
I purchased 40 units of Oripa for 600 yen per unit.
The cards were carefully packaged and each card was in its own sleeve, even the ones that were not.
The result was that I was lucky to win a small prize of +1000 yen, but I was able to win a lot of other people's prizes.
