PROBLEM TO BE SOLVED: To upgrade the durability against a secular deterioration by a fat excreted from a finger by forming a grip of the recycled material of a thermoplastic elastomer. SOLUTION: The forward part 1A of the barrel 1 of the writing utensil is formed to be of a small diameter and a cylindrical grip 2 is outwardly fitted to the forward part 1A. In addition, a tip 3 is screwed into the forward end of the barrel 1, and the grip 2 is pinched between the backward end 3A of the tip 3 and the stepped part 1B of the barrel 1. The grip 2 for this writing utensil is formed of the recycled material of a thermoplastic elastomer. The recycled material is preferably of a scrap called a runner which is generated in a plant. Thus it is possible to upgrade the anti-slip performance of the grip 2 for a finger and thereby minimize the generation of dust. |
