Made of fine-weave muslin with combed edges. Have 3/8" diameter arbor holes for use on 3/8" arbor shafts. Not for use on tapered spindles. Different diameters are available. Loose buffs are much softer and more flexible, follow contours easily, and are generally used for final polishing with rouge or other high-shine compound. All are 20 ply with an 80/80 thread count. Made in USA.
