Key String for USB Key??

[Goro]

Yes, yes I know. This is an insanely borrowing topic. But help me out anyway. I have bought a Sony USB key on the net and I was stupid enough to think that a key string (or is it called key strap?) followed with the product. But no! I would like to be able to carry my USB key around the neck but I can't seem to find any where on the net where I can buy a key string for USB keys. So if you have a link please post it.

Thanks!
