PROBLEM TO BE SOLVED: To provide a writing material system which enables arbitrary combination of writing materials in conformity with the use, with a writing implement as the core, as is the case of a portable personal filing system, and which is suitable for carrying and can be used also singly. SOLUTION: In this writing material system, a columnar base for setting the writing materials is constituted of a columnar recess which retains a columnar connecting shaft with a spherical protuberance thereof pressed therein and of the columnar connecting shaft which functions as a grip in the use and has the spherical protuberance provided at the fore end, and it is made of a synthetic resin and formed integrally. In the case when all or some of the writing materials are made of the synthetic resin and can be formed integrally, the whole of the all or some of the materials formed integrally is made a component. The components provided with the same or different kinds of materials formed integrally in the same way are paired and connected by pressing the respective spherical protuberances in columnar recesses, and the writing material system is obtained by combining the writing materials arbitrarily in conformity with the use by combining the components. |
