This 4" diameter, 50 ply, loose, Yellow Muslin Buff has been chemically treated which increases its thickness for better surface area coverage and rouge retention.  Lasts up to three times longer than untreated white buffs.  Loose buffs are joined only at the leather pinhole centers so they naturally provide softer action and are great at following contours.  Used for final, high-shine polishing.   Made of fine-weave muslin with combed edges. Highest quality thread count: 86/80. Made in USA.
