The term 'Unused Pieces' can be described as 'REMNANTS' (8 letters). Unused Pieces are items that have been left over from a project or activity and are no longer needed. These pieces may have been forgotten, overlooked, or simply not used. They can range from small items such as screws and nails to larger items such as furniture or appliances. Unused Pieces can be found in many places, including construction sites, warehouses, and even in people's homes.
