Review on 📸 2-Pack Sturdy Memory Card Storage Cases with 2 Micro SD Readers (USB) - Swiss Army Knife Style Design, Each featuring 3 Storage Blades - Holds up to 8X SD (SDHC/SDXC/TF) and 10x Micro SD (SDHC/SDXC/TF) Cards by Trey Angus

I love the idea behind this product Storing so many micro SD cards is perfect for all the different operating systems I work with as well as for image backup. Pros: Good size (a bit thicker than a pocket knife, but also a bit shorter) more than enough storage space Small but good USB to micro SD card adapter (it is recommended to use an SD to micro SD card adapter for a another slot next to the USB adapter) a bit loose (wouldn't trust a strap but more than enough for pockets) Micro SD card slots are very narrow, hard to plug in and out (but hey, they don't go anywhere, once they're in) Overall, if you're looking for card storage, I'd recommend MicroSD. Especially compared to those clear plastic single or double sleeves that you get with your SD cards. EDIT: About a week after I received this case and inserted my micro SD card into the provided USB port, the USB broke on my computer. I had to use a pickaxe to remove the broken piece. It's a pain which is why I took a star off my original 4 star rating. I wish this micro SD to USB transition was a little more solid.
