These lightweight, yet durable swabs help reduce and dissipate static electricity while attracting dirt and dust. Lint-free and non-abrasive, these swabs are gentle enough for even the most delicate surfaces. The black anti-static tips are manufactured from 100 PPI polyurethane foam that can withstand exposure to isopropyl alcohol. The stick and foam tip are joined with a chemically resistant adhesive. The 5 inch swab has a rectangular foam tip approximately 11/16 in wide x 1 in. long x 1/4 in. thick, while the 6 in swab measures approximately 3/16 in. wide x 11/16 in. long.
