I bought these for collection purposes and I was surprised that the price was so low compared to the suggested retail price. Thankfully, the box was delivered in pristine condition.
This box has all of the cards from the Detective Pikachu set and one Japanese exclusive card, so I'm happy to add it to my collection.
In terms of playing, from my limited but growing knowledge, there are some good playable cards in the box as well, so I would recommend this box to both players and collectors alike.
