Those are indeed disposable wrist straps to protect against static electricity damage
while installing electronic parts.  I used to work for a company where I received server
equipment from Sun Microsystems.  They came mostly assembled except for expansion RAM,
DVD drive, extra disk drives, PCI cards etc.  Each addon option was shipped with one of 
these.  I used to build up the systems using just one of these for the whole lot.  Since
I no longer work there, I don't have access to these and I never brought any home.  In
fact, my ex-boss pitched the remainder of the unused ones...  One end, for many inches,
has a light adhesive.  That end was for wrapping around the wrist.  You would probably
want to not use that piece.  They are about 3 or 4 feet long.  The fabric material is a
light gauze and is very flexible.  I can't say how durable the black material is, it's
very thin.  I'm pretty sure the black material is some kind of conductive plastic. 
Unfortunately, this is about a week late, I left the company last Monday...
