Review on 📸 Ultimate SD Card Case Storage Box: Waterproof, Shockproof, and Portable - Holds 4CF/4XQD 8SD 12TF 1SIM 2NANO SIM 2MICRO SIM 1Card Pin Slots Protector by Sean Castator

I was very satisfied with this storage box for SD cards. It is quite small making it easy to carry in your pocket or in your laptop side/zip pocket or travel bag. In fact, this thing has plenty of space for SD cards. There's also space to stack and mix types, so you could have up to 16 SD cards or 32 microSD cards if you stack them properly and they're all the same type. There is no "lock" mechanism or anything to lock the cards in place, but I found them to stay in place fairly well and pull out fairly easily too. It also comes with a tiny carabiner so you can attach it to a belt loop and the like if you want to go the "turbo nerd" route. Overall I'm very happy with this little case. It's nice to be able to keep all my SD cards in one place and it's perfect for my needs. I would definitely recommend it to anyone looking for a small and inexpensive storage solution for small memory cards.
