Washer Safe USB Thumb Drive

I've put enough electronics through the wash that I think this is a great idea: a Washer/Dryer Safe USB Drive.

I put my Audiovox Windows Mobile phone (SMT5600) through the wash a couple years ago, and I was amazed that it came out unscathed. So maybe these things are mostly washer safe, I don't know. Prefer to buy one that says it is, than find out the hard way.

Looks tiny too. My current USB drive is pocket-safe, thanks to its ability to retract the USB connector... I don't know how well this one would fare but I'm guessing probably pretty good.
