VFG 4.5mm - Match Set - Includes plastic-covered steel wire, grip disc, some 4.5mm Superintensive and barrel cleaners.
It is quick and simple to operate: push the wire through the barrel, fix the barrel cleaner on the adaptor and pull the wire through the barrel with the help of the grip disc. Repeat this procedure three or four times - and you're done. Oiling and deoiling works the same way.
