Review on Memory Card Storage Case With Micro SD Reader (USB) - Swiss Army Knife Type Design With 3 Storage Blades - Fits 5X SD (SDHC/SDXC/TF) And 2X Micro SD (SDHC/SDXC/TF) Cards by Mick Ohlrogge

I put together a fairly small handful of these micro SDs and kept them in a little zip lock in my flash drive case, which wasn't an answer. After losing a few of these due to the hassle of putting them in a small bag and then finding the used one again when I wanted it, I dropped one without realizing it and so on. I went in search of something new. That's a great idea! It's actually like a pocket knife, and the cards slide in securely but are easy to pull out if you want. Plus, it fits comfortably in my flash drive case, so I don't have to carry around two separate cases! Not what I had planned when I bought it! You have several different ones to choose from depending on what you need, even ones with SIM card slots. (FYI: The flash drive case is from Case Logic, but I don't think they sell that particular model anymore.)
