PROBLEM TO BE SOLVED: To make a writing brush longer to be easily usable when it is used, make it shorter to be compact so as to be handy to be carried when it is contained in a cap, and enable the length and thickness of a container to be freely designed. SOLUTION: A magnet 4 is attached to a bottom of a writing brush main body 1 in a main body container, and a magnet 4 is also attached to an inlet of a cap 3 to be brought into close contact with the writing brush main body 1 with the aid of magnetic force. By moving the cap 3, the writing brush main body 1 is stuck out from and retracted into the cap 3. |
