The 7DAYSHOP.COM compact storage case holds up to eight SD cards which is a useful size for modest travel tours. It does what it claims but I have two criticisms. First, it is not the easiest case to open, which can be frustrating when on location. Second, one of the imperceptible positioning tabs ruined one of my memory cards by breaking off the card locking tab when inserting the card for storage. Consequently the card could no longer be used for recording and was effectively destroyed. I have to ensure that cards are placed inside the case with extreme care, unlike older smaller cases I own which are less demanding.
