It's got a small metal ring on one end so that you can put it on your keychain, which is what I've done. If you're like me then you drop your keys on occasion. I've dropped them several times, with my flash drive attached. On concrete. Never a problem.
I've also opened my car numerous times in the pouring rain. Never a problem there, either. The USB connector is retractable, so it's okay if you go out in the rain or someone spills some cofee (or beer) on you. This also means you don't have to keep up with any easily loosable little caps for your flash drive.
I've owned four flash drives before this one, but there was always some kind of problem with toughness or convenience. This is the best flash drive I've owned, and I won't be trading it in for quite a while.
