PROBLEM TO BE SOLVED: To provide a cartridge for an ink replenishment by which the replenishment of an ink to a filler can be performed without fouling hands or a pen main body. SOLUTION: This cartridge 1 for the ink replenishment is formed of a plastic, and the ink 3 is housed inside. A tank section 6 and an insertion section 7 of the cartridge 1 are connected with a diameter-reduced section 9, and the upper end of the tank section 6 and the lower end of the insertion section 7 are sealed with sealing sections 5a and 5b. When the ink 3 is replenished, the sealing section 5b is cut off, and the distal end of the insertion section 7 is inserted from a nib-fitting hole 19. Then, the sealing section 5a is cut off, and the ink 3 is replenished. |
