The bristles are made of soft nylon that are carefully hand tied into a high-quality soft-bristled brush with Delrin handle (pharmaceutical grade). The brush is tough enough to easily clean away grime and dirt, but soft enough not to damage your watch. One row of soft bristles ensures an ability to clean tight areas. A much safer and more gentle alternative than a toothbrush! Enjoy the best! Size is 6.5″ × 1″
