First, the description of the package gives the impression that there are 4 earbuds, actually 5 (4 different styles) a MemoryStick/ Full Size Pro Card (or Duo Adapter) 1 Insert for 1 SD Card and 8 Micro SD/TF Cards. The case holds 2 earplugs at the same time. as shown in the photos. The case itself is thin aluminum, so the middle section (with the lugs) bends relatively easily (plus and minus since you can tighten or loosen the lugs to open or close the case). too simple). I haven't had a problem with it opening too easily, but I'm not rough on the case. I have a similar case that opens about 150 degrees - and it's annoying. This case opens 180 degrees to lay flat! I have already ordered a third sleeve and will be storing ALL my cards (except MicroDrives) in it. It would be handy if I could order an empty case to use some of the extra earbuds, but that's not really a complaint, just a desire not to miss something useful (the "extra" earbuds).
