Flexible Gap Cleaning Brush

A brush is a tool with bristles made of hair, wire, metal, synthetic fibers, or various natural materials that are attached to a handle made of wood, plastic, wire, or metal. Some varieties of brushes are adapted to be connected to power tools for heavy duty work such as removing paint or smoothing metals or dust.
Your water bottle or cup cover or key board builds bacteria and dust especially in the book and cranny of the lid.
It is difficult to clean the corners and hence you need the brittle brush to.
