Pre-stretched, but I wouldn't personally re-use galvanised spokes. IME
they do start snapping with age, and they look horrible after a year on
the bike anyway.

Old spokes are fine, but they do take a set when built up into a wheel
and have to be re-used in the same relative position (heads out or
heads in).
