I looked at the box risen so that the various cards are not always "somewhere" but always be stored at a particular location. Delivery and so on, as always top. Yesterday I then, really just for fun, the held part time under water and it came out at different places bubbles. Thereafter, water was in the box - not much but still. For me no reason to complain because I do not want to take the plunge, the part. Memory cards are not the same broken when times comes a drop of water on it ... But why the water penetrates I can not explain it. Both the box and the seal show no visible damage. No matter - I would buy anyway again.
