PROBLEM TO BE SOLVED: To facilitate a classified disposal for every material by attaching a pen tip, a core material impregnated with ink, and a housing body for wrapping the core material to put them together, and detachably fitting the tip end of a tubular main body shaft for surrounding the outer circumference of the housing body to the pen tip holder. SOLUTION: A felt-tip pen comprises a felt-tip pen main body 1 and cap 2, and the felt-pen main body 1 is provided with a pen tip 4, a core material 5 impregnated with ink, and a bag body 6 of a housing body for the core material 5 in a manner being integrally secured to a pen tip holder consisting of resin material such as polypropylene. The tip end of a paper-made tubular main body shaft 7 for surrounding the outer circumference of the bag body 6 is detachably fitted with respect to the pen tip holder 3. In this structure, resin material necessary for constructing the felt-tip pen can be greatly diminished, and the main body shaft 7 and pen tip holder 3 can be easily classified in the disposal of felt-tip pens after use, and the paper-made main body shaft 7 can be disposed as combustible refuse. |
