A disposable brush formed of a nonwoven fabric or of a pulp molding which comprises a base and a number of projections formed on one side of said base by allowing portions of said base to project,
- wherein said base is a sheet base and has a slit in the peripheral portion thereof so that said brush can be held by hand by means of said slit.
A disposable brush formed of a nonwoven fabric or of a pulp molding which comprises a base and a number of projections formed on one side of said base by allowing portions of said base to project,
- wherein a water-retaining member is provided on the reverse side of said base, and
- wherein said water-retaining member comprises pulp and a water-absorbent polymer, and the outer surface of said water-retaining member is covered with a cover sheet.
A brush, formed of at least one of a non-woven fabric or a pulp molded product, comprising:
- a base formed of a single layer;
- and
- a plurality of projections formed on a surface of the base,
- wherein the plurality of projections is formed from portions of the base that protrude from the surface of the base, and
- wherein the base has a height toward a center portion that is greater than a height toward a peripheral portion, wherein the non-woven fabric includes at least one of a spun lace non-woven, a spun bond non-woven, a suction non-woven, a heat bond non-woven, a melt blown non-woven, and a needle punch non-woven.
