Lost my thumbdrive cover

I lost my thumbdrive cover today.

It was when analysing my SD card reader that I realised that this
could have been averted if the thumbdrive cover is somehow connected
to the thumbdrive. Which is actually possible SanDisk thumbdrive - I
could have connected it with a piece of thread to the thumbdrive
'jacket'. Oh well...

Found this article which indicates it is not really that critical to have one... But still it feels right to have it... Any unwanted SanDisk thumbdrive covers, anyone? it's that bad feeling I get when I lose stuff, like my Timex watch after the 2005 Sem 1 exams...

EDIT: I found my thumbdrive cap! and made some slight modifications to ensure it will not go missing again...
