Abstract: An accessory decorates diverse articles of manufacture, by being mounted on a flexible, elongated, support element, e.g., a wire of a headphone assembly, or a string of a bracelet assembly; or by being mounted on support surfaces of clothing, such as hats, shoes, pants and shirts, or other items, such as protective cases for mobile electronic devices, or sleeves supported by eyeglass frames. Multiple such decorative accessories are collected in a kit, and are mounted on any of such articles and interchanged, one with another.
