Ok, perhaps some more explanation is needed.
This little book locket is made in sterling silver and is about an inch tall. Inside is a miniature 8GB USB memory stick. The USB port bit is actually larger than the memory itself.
I found this mini USB memory and wanted to make a locket for it.
By chance I started working on a "Hitchhikers' guide"-themed pendant and remembered the tiny USB in my bag...
Manufacturing time (after solving various design isues) about 5 hours.
