10 Slots Micro SD Card Case Holder Storage Organizer, Ultra Slim Credit Card Size Lightweight Portable TF MSD Memory Card Storage...

I feel they are secure in the individual slots, nothing can damage the cards with them being totally enclosed. However I just have a concern that they could fall out if the holder is dropped. Therefore, I plan on keeping the whole thing is a small case, along with my other storage media, that snaps shut. Still way better than the cards just loose in my little case, and I like the white area that allows me to label them individually.

Perfect size. Clear to see thru - so you can see each chip. Really great execution of a simple idea.

Great way to store sd cards to prevent them from getting lost, the form factor is great because it can slot into most things that hold credit cards, but the micro so card slot is extremely tight. Youll have to use pliers to get them out when fully pushed in. I guess too tight is better than too loose, but would be better if it were just a bit looser or if it had one of those push to eject mechanisms. Overall though great way to store so cards and does so at a great price.

Bought this to store my many SD cards and not worrying about losing them. Its very small and compact which I love as it packs away really nice inside my DJI Drone carrying case. It stores 10 MicroSDs with the ability to label them on the backside for your own convenience. Also has a hole through one corner if you are looking to attach it to a key chain, bag, etc. Highly recommend it for storing your Micro SDs! Summary: 10 Slots+ Super Small+ Strong Plastic build+ Hole for a keychain/attach to bag+

MicroSD cards have effectively taken over the role once served by floppy diskettes... the standard for removable, portable storage. And yet, with their tiny size, they're far more easily lost than any prior storage medium. There are a variety of options for storage of these tiny little cards, from large boxes with slide-out trays to little foam pads inside of zip-close pouches. Some are more convenient for shelftop storage, some for portable use. But none I've encountered are quite a "portable-suited" as this design. In my own case, I use this with my Raspberry Pi mini-computers. Raspberry Pis do not yse a physical hard disk... or solid state drive... for storage. Instead, they store everything on MicroSD cards. So, by swapping the card, you can essentially totally transform a Pi into a "totally different machine." I have several cards, for several operating systems and roles. One card us a standard Raspberry Pi "Rasbian" operating system. Another us Ubuntu Linux. Another is "RetroPi," an installation which mimics arcade and console hardware. And so on. The Raspberry Pis I use are extremely portable... my tiny little Zero 2W, and my larger but still pocket-sized 4B. I have a tiny, foldable Blutooth keyboard & touchpad combo, a superthin fiber optic HDMI cable, and a tiny "wall wart" power source. I can carry every part of this in one jacket pocket without the pocket bulging. Except, I was limited, oreviously, to just one OS card, because carrying more required significantly more bulk for a card "wallet,"or required loose cards able to be easily lost. That's where this comes in for me. I can carry quite a few cards, all in their assigned places, so no need to "sort" when I want to swap, and in a form factor both convenient to carry (even in my wallet, though normally in with the Pi itself) and yet difficult to lose. I would not encourage using this for at-home or at-office organizing of a large library of cards. There are far better options for that, I think. Certainly more space-efficient ones, too. But for safe, well-organized portable card storage, this is my favorite approach, by far. As a side note, there are several variants of this in ZeeBooth as I write this review. All seem to be physically identical, manufactured in the same factory from the same production tooling. The only differences seem to be related to marking and branding. So, pick the one whose markings you like best, but don't bother, beyond that, figuring out if one is "better" than the next... they're the same, in every meaningful way.
