A capless, retractable, writing instrument consisting of two distinct actions, one to extend the ink cartridge tip for writing and another distinct action to retract the ink cartridge tip. The writing instrument includes a plunger which is pressed to push the ink cartridge tip outside the body of the pen and a side mounted button retains the extended ink cartridge while writing. The side mounted button is pressed to retract the ink cartridge tip inside the body of the pen for safe storage. The writing instrument contains easily manufactured components.

A single-use surgical marking pen assembly is disclosed. The assembly comprises a housing configured to at least partially receive an elongated member having a first end and a second end. The first end is attached to an ink cartridge terminating in an ink tip while the second end is engaged with a stopper. A plunger end is configured to selectively retract the ink tip into the interior cavity of the housing via the elongated member. A circumferential band is configured to releasably engage with a cap configured to conceal the ink tip when engaged with the circumferential band. A stoppage is positioned on an interior surface of the housing to restrict the movement of the stopper, the restricted movement of the stopper prohibits the extension of the ink tip.

An electronic pen has increased strength, especially a pen tip portion that is not bent or broken even if the electronic pen is slimmed down. A core unit includes a ferrite core on which a coil is wound and a core rod. The core rod is fixed from a first end of the ferrite core to a second end of the ferrite core at a position including a center axis of the ferrite core and projects at an end thereof from the first end of the ferrite core. The ferrite core includes a first coil non-winding portion on which the coil is not wound provided on the pen tip side of the ferrite core. In operation, the end of the core rod and part of the first coil non-winding portion of the ferrite core project from an opening of a housing of the electronic pen.

Provided is a coating film transfer tool comprising an external cassette and an internal cassette housed in the external cassette. The internal cassette includes a supply portion configured to supply transfer tape having a coating film on substrate tape. A pressing and transferring portion is configured to transfer the coating film to a film receiving surface by pressing the transfer tape against the film receiving surface, a take-up portion is configured to take up the substrate tape after the coating film is transferred, and a rotation-in-conjunction mechanism is configured to rotate the supply portion and the take-up portion in conjunction with each other. The external cassette includes a button and an elastic member. The pressing and transferring portion sticks out of the external cassette by the button being pressed, and the pressing and transferring portion retracts into the external cassette by the pressing of the button being stopped.

A pressurized-type writing implement includes: a shaft tube capable of housing therein a refill filled with a writing implement ink composition; and a pressurizing mechanism that applies a pressure to the writing implement ink composition; the pressurized-type writing implement being capable of switching a writing state in which a front end part of the refill projects from a front end opening of the shaft tube, and a not-writing state in which the front end part of the refill is retracted from the front end opening of the shaft tube, wherein the pressurized-type writing implement has a pressurizing-force adjusting mechanism that adjusts the pressure.
