RIVEENY 5-Pack Silicone USB Cases - USB Flash Drive Protectors

These are very nice quality, I do WISH they made these for YubiKeys also since they all have the exposed ends. If the company actually reviews these please consider making these for the YubiKeys!

Perfect for minimally sized thumb drives.

I bought these for my new Yubikey but when they arrived, I was surprised how small they actually were. My Yubikey was too wide to fit but I think the length would've been OK. The "lanyards" that came with them were very pretty. I don't know how much use I could have gotten out of one because the material seemed thin and too delicate to take normal wear & tear for any extended period of time. Perhaps that's why there's 5 in a pack? The set up also didn't really work well with my key chain.

I don't know what these are designed for, but they are not large enough to hold standard NFC Yubikeys.

These are very good and with all the different colors it let me know what I scored on each one perfect

Durable silicone and strong cord for hanging from a backpack or key ring. I love have the different color options, helps with organization.

When in use the usb stick slips out all the time. A good way to lose the USB stick. The pocket is too small for proper protection.

I thought these would be a good idea for keeping dust from my USB sticks. I wasn't really looking for the portability but that would have been nice too. Not one of my 7 thumb drives fit in these, not even close. Not worth getting.
