The box itself is good and legit. Although korean pokemon cards feel a bit more like a "fake" card, probably due to how its printed. The colors are a little saturated and the card feel more smooth like a wax card. But all the texture holos are correct, just the feel of the back.
This was the first order from Sakura that I felt disappointed. The delivery took a month since order was placed. The package delivered in left a lot of room where the boxes were 100% shaken around causing small dents on the boxes, but nothing that will damage the cards itself. I have also been waiting 2weeks+ to get in contact with Sakura and I've tried web chat, email, discord chat, X posts.
