A friction body is configured to discolor handwriting written with a thermochromic ink with frictional heat. The friction body includes a viscoelastic body, and has a Shore A hardness (based on JIS K 7215) immediately after start of contact of an indenter point of from 55 to 95.

A retractable marker assembly includes a tube that has a tapered end such that the tube has a conical shape. An ink cartridge is insertable into the tube and the ink cartridge contains a fluid ink. The ink cartridge is slidable between an extended position or a retracted position. An applicator is fluidly coupled to the ink cartridge to absorb the fluid ink contained in the ink cartridge for marking a surface. A cap is removably attached to the tube and a button slidably extends through the cap. The button engages the ink cartridge and the ink cartridge is positioned in the extended position exposed when the button is depressed having the applicator being exposed. The ink cartridge is positioned in the retracted position when the button is not depressed having the applicator being withdrawn into the tube.

An input touch pen includes a digitizer refill contained inside a shaft tube and including a contact tip and a stepped tip portion rearward thereof, and a knock member protruding from an opening at a rear end of the shaft tube. The contact tip can protrude and retract through an opening at a tip end of the shaft tube. The stepped tip portion has a larger diameter than the opening at the tip end. A relationship A>X>Y is satisfied, wherein X represents a knock stroke of the digitizer refill, A a distance from the stepped tip portion to an inner surface at the tip end side when the contact tip is sunken inside the opening, and Y a distance that the contact tip is moved by operation of the knock member from a state of protruding from the opening to a state of being sunken inside the opening.
