A lint roller in use. A lint roller or lint remover is a roll of one-sided adhesive paper on a cardboard or plastic barrel that is mounted on a central spindle, with an attached handle. The device facilitates the removal of lint or other small fibers from most materials such as clothing, upholstery and linen. Once expended, the roll can typically be replaced with a refill roll. Invented in 1956 by Nicholas McKay, Sr., his most well-known (and first commercial) product was the Lint Pic-Up, the world's first lint roller. Reusable lint rollers use elastomers, including silicones and polystyrene-ethylene-butylene-styrene as a reusable tacky surface.
