The Memory Card Case Hama accommodate 4 pieces memory card, is made of soft material and is closed with Velcro. The 4 cards are simply pushed into the designated small bag, which need not be specially sealed. I find the Card Case very convenient because it is small and portable and therefore can be plugged super for example in the camera bag. The material could eventually can be somewhat stronger, the cards are in fact not very well protected in this bag. I would not trust this bag to put in my pants and then sit on it - the memory card could bend. But since this is not an essential requirement for me, I like to give 4 stars for this product - the value for money is very good in any case.
