Abstract: The invention relates to a marker with a seal arrangement, comprising a housing in which an ink storage chamber, a spring system, a writing tip connected to an end portion of the ink storage chamber, and a seal arrangement fitted onto the outer periphery of an end of the writing tip are disposed. The seal arrangement comprises a frame portion and a sealing chamber fixed on the frame portion. The sealing chamber has an opening at its front end for the writing tip to protrude and retract, the frame portion is fixed at its front end with one end of a tough and flexible sealing strip which has the other end fixed on a hooked block formed at the front end of the ink storage chamber, the sealing strip further comprising an aperture capable of closing and exposing the opening of the sealing chamber.

Abstract: An illuminable writing instrument includes a writing unit holder to receive a writing unit, and an illumination arrangement including a light dispersing cone having a cone vertex supported within the writing unit holder, an illuminator supported within the receiving cavity at a position right above the cone vertex of the light dispersing cone, and a control switch arranged to activate the illuminator for providing an illuminating effect towards the cone vertex of the light dispersing cone, such that the light dispersing cone is adapted for vividly dispersing the illuminating effect throughout the writing unit holder.

Abstract: An illuminable writing instrument includes a hollow elongated body having a first end, an opposed second end, and a receiving cavity, wherein the elongated body is adapted for a light passing from the receiving cavity to outside, a writing unit, having a writing tip, disposed in the receiving cavity, an actuator mounted at the second end of the elongated body to move the writing unit from a normal unemployed position to an operation position, and an illumination arrangement including an illuminating unit supported within the receiving cavity of the elongated body and a switch control which is electrically connected to the illuminator and is arranged to activate the illuminating unit for providing a lighting effect throughout the elongated body while actuating the writing unit via the actuator.
