PROBLEM TO BE SOLVED: To secure a sufficient air flow path by forming a nib member out of a porous body, in writing utensils in which a writing body is incorporated in the inside of a barrel and the writing body is projected from the projection hole of the nib member freely detachably fitted to the tip of the barrel. SOLUTION: The writing utensils are constituted by incorporating a writing body in the inside of a barrel cylinder 1 and projecting the writing body from the projection hole of the nib member 9 freely detachably fitted to the tip of the barrel cylinder. In this case, an air flow path 12 is formed in the middle part of the nib member. In the writing utensils, the writing body is incorporated in the inside of the barrel cylinder and the writing body is projected from the projection hole of the nib member freely detachably fitted to the tip of the barrel cylinder. The nib member is formed of a porous body. |
