This Jewelry Cleaning and Polishing Cloth is for Gold, Silver, and Platinum. The 10"x14" (when open) 100% cotton flannel inner cloth is thouroughly impregnated with non-toxic cleaning and polishing agents especially formulated for fine jewelry and contains a tarnish retardant." This cloth can be used over and over, but do not wash it. I polish a lot of silver and one lasts me about 2 year. The exact color and packaging of the cloth can vary.
