Loose muslin buffs have 1 row of stitching (near the arbor hole which is 3/8" dia.). Originally conceived for polishing tin-based metals, they work just as well on all soft metals. All have 20 plies and are available in yellow for cutting and white for finishing. Typically 2 or more are grouped together until the desired width is attained. Used with 1/2" straight arbors only. Not for use with tapered spindles. Made in USA.
