These 6x36 ply Razor Edge Plum Buffs have 11 rows of stitching.  Can reach into areas where conventional buffs cannot, such as corners, channels and slots. Stitching provides firm edge and maintains buff shape. Plum buffs are chemically treated to impart an amazing finish on precious metals. The special treatment creates a firm buff and greatly reduces wear. Plum Muslin Buffs retain compound extremely well, producing a brighter finish than other buffs.  Made of fine-weave muslin with combed edges; all with highest quality thread count of 86/80. Leather centers hold buffs firmly on tapered spindle. Made in USA.
