  • Patent number: 8678691
    Abstract: A writing implement. A tubular outer shell (11) is provided outside a grip member (10), an inner shell (12) made of a soft material is provided entirely inside the outer shell (11), and the inner shell (12) is covered with the moderately hard outer shell (11). Thus, while the inner shell (12) inside can allow the user to feel the fit, the outer shell (11) outside prevents the inner shell (12) from getting damaged or worn even if the inner shell (12) is soft, so as to fully secure durability of the grip member (10). Since a thin part (11A) of the outer shell (11) is sufficiently thin on a swell (13), the excellent fit can be given to the user even if the outer shell (11) is formed of a hard elastic material to fully secure the durability of the grip member (10).
