The invention also pro- vides a writing instrument for a specific liquid which has a liq- uid passage for supplying the liquid at all times from a liquid reservoir having multiple liquid passage holes which are longitu- dinally elongated and spaced apart from each other to a brush point through a liquid supply cylinder located between the reser- voir and a brush point which has liquid outlets at a peripheral wall thereof, so that at least one of the holes and outlets is always aligned to let the liquid through. The invention again provides a writing instrument for a specific liquid which has a mouth element and a mouthpiece member and a liquid reservoir which has a valve box/cylinder and is connected with the mouth element having a packing having a concave portion which forms a cavity adjacent to a wall surface of the packing groove; and the invention again provides a writing instrument for a specific liq- uid having a cap over a brush point, said cap being adapted to detach from the brush point and be inserted into a concave por- tion of upper portion of a shaft sleeve so that a lower end of the cap may be placed on an upper end of an ink bottle or piston stem thereby supplementing the knocking movement.
