A marker and stamp system embodied in a double-end device is provided. The device includes a marker end and an opposing stamp end. The stamp end enables the creation of clear and concise group presentations/instructions through the uniform application of predetermined symbols via a stamp applicator portion and marking template, while the marker end facilitates the presentation of tailored, free-hand markings via application of a marker nib.

A feeding pencil includes a main body, a leading tube, a middle tube, and a ratchet mechanism. The middle tube is engaged to the leading tube to be relatively rotatable. A relative rotation between the leading tube and the main body in one direction moves a drawing material forward. The ratchet mechanism allows the relative rotation between the leading tube and the main body in the one direction, and regulates the relative rotation in another direction. The ratchet mechanism includes an elastic projecting part and a concave-convex part. The concave-convex part engages with the elastic projecting part to be movable in an axial direction and rotatable. A protrusion disposed at a center tube removably engages with an annular convex part disposed at an outer surface of the leading tube in the axial direction.

An applicator includes an approximately cylindrical-shaped body, a core-like application member, a storage for a liquid applying material, a liquid applying material absorbing body that adjusts an amount of impregnation, and a plug that causes a rear end side of the application member to be inserted through an insertion hole to hold the application member. The plug exposes the rear end side to a side of the storage. The insertion hole has a shape in which a clearance width with the application member is adjustable according to viscosity and a material of the liquid applying material to make an amount of the liquid applying material adjustable. A storage region is configured to be increased and decreased by changing a position of a stop plug. The absorbing body is mounted to a distal end and has changeable length and size configured to increase and decrease the amount of impregnation through cutting.

A handheld spinner includes a housing, a holder, a ball bearing, and a stationery item. The stationery item is disposed on the housing and includes a pencil, a pen, a marker, a highlighter, a crayon, a brush, a stylus, a stamper, an eraser, and/or chalk. The ball bearing is disposed in the holder and the holder is disposed in the housing. In one embodiment, the handheld spinner includes a cap disposed on the holder and the ball bearing. In one embodiment, the handheld spinner includes a holder, a ball bearing, and a stationery item. In one embodiment, the stationery item is a plurality of stationery items spaced apart by discrete angles. A user rotates the handheld spinner about the rotational axis of the ball bearing, which spins the stationery item or items. The handheld spinner is useful as a fidget toy and houses multiple stationery items on a single device.
