发明名称 WRITING IMPLEMENT FOR WATER DISCOLORATION BODY
摘要 PROBLEM TO BE SOLVED: To provide a writing implement inexpensively by decreasing the number of parts, to prevent a writing trace from being cut by supplying water promptly to a whole pen point even when the pen point is large in size, and to prevent the leakage of water from a water tank during the supply of water. SOLUTION: The writing implement 1 has the pen point 2, the water tank 3, a communication hole 41, and a holding hole 42. The pen point 2 is made of a fiber processing body or a porous synthetic resin body. The water tank 3 is flexible, and the pen point 2 is fixed. The communication hole 41 connects the pen point 2 directly to the water tank 3. The inside diameter of the holding hole 42 is larger than that of the communication hole 41, and the pen point 2 is held by the holding hole 42.
