Black Magic Barrel Swivels 4kg. Pack 32.

The Wasabi Tackle Black Barrel Swivels are used
for line-to-line leader connections and for setting up float and
running sinker rigs. These rigs reduce line twist and they can also
be used to make your own pre-rigged line traces. And what's more
each swivel has a black finish that helps to stop the likes of
barracuda or other tooth fish from biting them and snipping off
your trace.
