By selecting and applying a specific material and a specific range of its melt index and hardness, we can obtain a pen body with the desired ink capillary passage shape, and achieve proper ink drawability, a soft writing feel, and abrasion resistance. It has been found that the resin satisfies solvent resistance, and more specifically, in a pen body for a brush pen of the type in which an ink hair II tube passage is formed in the 114m direction by melt extrusion processing of a synthetic resin, the resin is heated. plastic polyurethane elastomer,
A polyester elastomer or a polyamide elastomer, and these resins are synthetic resins with a melt index of 0.5 to 5.0 g/10 min and a hardness (Shore D) of 30 to 60. do.
