Sweater Stone is a natural pumice which has the unique ability to remove pilling/lints from knits with each sharp edge of a broken cell. It actually cuts the filament that holds the pills/lints to the garment while the cell breaks off, removing pilling/lints and restoring the nap on fabrics.

 Pilling/lints commonly occurs on a fabric when fibers that are worked loose by rubbing, form little balls. The pills/lints don’t fall off because they are held to the fabric by the fibers that still hold firm. Loosely woven and knitted synthetics and blends are the typical candidates for pilling/lints. Usually, it’s the stronger synthetic fibers that hold the pill/lint to the surface. Pilling/lints can happen to clothes, blankets, and upholstery fabrics. However, sweaters seem especially vulnerable.
