Abstract: An assembly comprising, an attachment; and a container, the container including a main body and a tube section, the main body forming a storage space, the tube section having an opening that communicates with the storage space, the tube section having an outer circumference surface provided with a first engagement section, the first engagement section having a first surface facing a first direction that is a direction toward the storage space, the attachment including a ring-shaped section that is fittable with the tube section, the ring-shaped section having an inner circumference surface provided with a second engagement section, the second engagement section having a first surface facing a second direction that is a direction away from the storage space, the first engagement section and the second engagement section being engageable with each other when the first surface of the first engagement section abuts on the first surface of the second engagement section, drag force in the second direction being larger than drag force in the first direction, the drag force being force for the first engagement section or the second engagement section to go over each other.

Abstract: Provided is a brush head for cleaning a surface of skin of a face. Tip-end-curved bristle bundles and tapered bristle bundles are implanted in a plurality of implantation holes of an implantation base portion so that the tip-end-curved bristle bundles and the plurality of tapered bristle bundles have the same height. The tip-end-curved bristle bundles are implanted in implantation holes at an outermost peripheral part of the implantation base portion, and form an outer-peripheral tip-end-curved-bristle bundle group. The tapered bristle bundles are implanted in implantation holes in an inner region relative to the outer-peripheral tip-end-curved-bristle bundle group, and form an inner tapered-bristle bundle group. The inner tapered-bristle bundle group includes a center tapered-bristle bundle row formed of ones of the tapered bristle bundles, the ones being implanted in implantation holes on a center cross line that crosses a center of the inner region, and other ones of the tapered bristle bundles than the ones forming the center tapered-bristle bundle row and the tip-end-curved bristle bundles are implanted in a symmetrical arrangement on both sides relative to the central cross line.
