Abstract: A glittering writing/drawing material composition includes a solvent, a lustrous particle having metallic luster and dispersed in the solvent, and at least one dye dissolved in the solvent. A hue difference between a first hue and a second hue is 108° or less in a hue circle in a Munsell color system, where the first hue is measured on the lustrous particle in a solid state with a spectrocolorimeter, and the second hue is measured on a liquid composition obtained by removing the lustrous particle from the glittering writing/drawing material composition and applied on a white wood-free paper with the spectrocolorimeter. The lustrous particle has a coverage of 1.0% or more and 70.0% or less on a surface layer of a drawing object formed by the glittering writing/drawing material composition.
