Long fiber cotton and a twill weave create a "hard" finish with plenty of criss-crossed, woven, "teeth" for an aggressive scrubbing action that removes heavy fouling and works great for applying cold blues, too. Lint is virtually eliminated; you can apply oil in action recesses without leaving patch fuzz behind. Sizes are smaller since patches are thicker. Mfg: Brownells SPECS: Sold in packages of 1000.
