A ball-point pen is provided to prevent glancing marks even in using a thixotropic aqueous ink containing paints with the large particle diameter like glass flake paints or glittering paints. The ball-point pen(1) is composed of an ink receiving part(7) and a ball-point pen tip(5) connected to the correspondent ink receiving part. A ball(10) is rotatably disposed at the ball-point pen tip with exposing a portion of the ball. A thixotropic ink is contained in the ink receiving part. The ball moves axially about 60~170mum in the ball-point pen tip. The aqueous ink containing paints with different particle diameters is filled in the ink receiving part. The maximum particle diameter of the paints is within a range of 40-200mum. |
