Stippling instrument

A stippling tool comprising:

• a cylindrical main body having an opening on a distal end side thereof, and defining an ink containing chamber therein;
• a slender ink transfer member having a proximal end portion to which ink in the ink containing chamber is supplied, and a distal end portion extending to the opening of the main body, in which ink is transferred from the proximal end portion to the distal end portion;
• and
• a porous elastic stippling member provided on the distal end portion of the ink transfer member, through which the ink permeates;
• the stippling member having a stippling distal end surface outwardly projecting in a curved shape, and located outside from the opening of the main body, the distal end surface being elastically deformed by a stroke pressure, thereby stippling a point mark of dimensions in accordance with the stroke pressure onto an object material,
• wherein the stippling member has a cylindrical circumferential portion enclosing the distal end portion of the ink transfer member such as to be in contact therewith and having an opening at both ends, and a distal end portion which closes the opening on the distal end side of the circumferential portion and includes the stippling end surface.
