PROBLEM TO BE SOLVED: To provide a structure to manufacture small volume production products in various and diversified design with a small load on the environment using existing manufacturing facilities reducing high initial investment in development of a manual brush. SOLUTION: This manual brush is separated in three parts of a stem part 1, a head part 2, and a main body part 3. The parts are manufactured without specifying materials and methods. The head part 2 with a brushing function most quickly worn is standardized (to be a standard part) and joint parts of the parts are given functions to mutually fit and to securely/easily combine and separate.
