Grands love them
Perfect for trips. Small enough to not be bulky. Grands love them and have competitions on which can write math problems quickest. Comes with a cheap sleeve protector, tore at the start. I use a Ziploc bag now.

A little expensive but worth the money
It's hard to find small containers like these for micro sd cards. I bought two of these and they arrived as pictured. They seem well made and have a silicone ring to help keep water out. It takes a few turns to unscrew, so the lid is not likely to come off by chance. At $20 each they are a little pricey but they are pretty unique and one of the only options if you want to carry micro sd cards with your keys. There was a small nick on the outside of one of mine where I assume a machine chipped it but it was probably a fluke because the other one was fine.

Very well built and not too big when attached to a keychain or carabiner clip
It is exactly as advertised, and looks very sturdy -- no weak points in the design or materials that I can see. It even comes with a small foam plug to keep my several microSD cards from rattling around (the storage space is ~40% larger than a microSD card) . It takes amost 2 full turns of the cap to close or open it, but that's a Good Thing. On a keyring, other people might think it's a pill caddy and not your precious data. Well worth the price in my opinion.

Small and lightweight, yet sturdy
I've had multiple USB thumb drives break apart on my key ring, I needed another way to carry files with me. Putting microSD cards into a container like this is brilliant! I just received it today and I'm surprised at how lightweight and tiny it is. Really happy with this, thinking to buy a few more for backup.
