The case does what it's supposed to - holds 12 SD cards securely. The case is translucent so you can see the SD cards inside the case and determine their capacity. However, the maker of the version I received (Acuvar) chose to emboss their name in white on one of the card slots, making it difficult to identify the card inside. Essentially, each box contains 11 identifiable cards plus one "Mystery" card. An annoying but not fatal design decision.
