A small silk cloth for special items used in the Japanese tea ceremony. Kobukusa are often intricately woven, small silk fabrics with patterns or often woven gold thread, known as kinran (kin - gold, ran - thread). In the tea ceremony, they are used to draw attention to certain items, such as a special tea bowl. A kobukusa can also be used when a tea bowl is very hot, so that the hands are not exposed to the heat when drinking. Translated with DeepL.com (free version)
