Brownells Super Duty Pipe Cleaners 6" Package of 360

The best cleaners we've found for pin and screw holes as well as slots and grooves. Recommended to us by Thomas Getzen, they have tough plastic bristles worked into traditional pipe cleaners. Think of them as tiny scrub brushes with built-in mops. After the bristles loosen dirt and fouling, the mop holds all that crud and carries it out of the hole. Available in package of 360 or box of 720. Mfg: Brownells SPECS: 6" (15.2cm) long x 1/8" (3.2mm) diameter.
