brush holder

A brush holder is a traditional tool used in calligraphy to hold brushes when they are not in use. It is typically designed to keep the brush upright, preserving its bristles and preventing damage. Brush holders come in various shapes, materials, and designs, depending on the culture and era they are from.

In Japan they may be called "fude kake", whereas in China they may be called "bi gua". These terms loosely translate to "hanging brush", as these holders have the brush suspended upside-down.
