An application container includes a main body cylinder, an application tool, and an engagement portion. The main body cylinder has a first end and a second end opposite the first end. The application tool is insertable into the main body cylinder through the first end of the main body cylinder. The engagement portion is positioned within the main body cylinder, and includes a cylindrical portion to connect with the application tool and a connector that connects the cylindrical portion and the main body cylinder. The cylindrical portion of the engagement portion is spaced apart from the main body cylinder.

A composite writing implement according to an embodiment includes a barrel, writing shafts housed in the barrel, a cam main body including a cam projection, an end surface extending along the cam projection, and a latch recess provided in the cam projection, and sliders configured to be connected to respective rear ends of the writing shafts, and include a cam configured to be latchable to the latch recess, and have a sliding contact surface to be pressed against the end surface, wherein the end surface includes a first inclined portion that is positioned on the front end side of the cam projection and is inclined by a first incline angle, and a second inclined portion that is positioned further toward the rear end side of the cam projection than the first inclined portion, and is inclined by a second incline angle that is larger than the first incline angle.

A manual device extends in an axial direction and includes a housing having a first housing portion and a second housing portion. First and second heads are each axially movable between a use position and a stowed position. The first head is in the stowed position when the second head is in the use position, whereas the second head is in the stowed position when the first head is in the use position. The first head and the second head both are carried by a single carriage movable in the axial direction and arranged inside a barrel. A groove forming a cam track is formed by a first shoulder of the first housing portion and by a second shoulder of the barrel. A lug of the carriage cooperates with the groove.
