The delivery took scarce 3 weeks (came from Asia) and then I got to see, unfortunately, is worth only 1 star.
2 Of the 10 cases are immediately landed in the trash because they are strong torn on first opening the opening angle. Of the remaining 8 cases 3 were strong and 2 slightly dirty. As one reviewer wrote here already right there are small black spots that disappear by scraping.
All this would perhaps give another 2-3 star, but the cases are unfortunately too big on the depth. An SD card only as rattles around in the envelope. One could almost put two cards in an envelope.
Conclusion: Long wait + poor quality + + pollution wrong fit = 1 Star
