Provided is an electronic pen stylus including a front-end part which, in operation, comes into contact with a position pointing input surface, and a rod-shaped axial center part formed integrally with the front-end part, in which at least the front-end part is made of a filler-mixed resin of which a base resin is mixed with a fibrous material as the filler having a hardness that is higher than a hardness of the base resin.

A golf ball marker for applying chalk to a golf ball. The golf ball marker includes a housing having two space ends and in which one end is dimensioned to support a golf ball. A plunger is slidably mounted in the housing while chalk is carried at the end of the plunger. Consequently, upon movement of the plunger towards the golf ball, the chalk contacts and marks the golf ball.

Devices, kits, and methods for manipulating crayons to make various crayon configurations are provided. Embodiments of the invention include a crayon slicer, a crayon shaver, a crayon holder, a crayon notcher, a crayon shaving kit, and a crayon rubbing kit. The multiple embodiments of the invention have various features that allow for a crayon to be easily and safely manipulated by a user in multiple ways. Further, additional embodiments provide additional features, which allow the user to make various crayon configurations.

A marking device that is supported by a personal mobility vehicle, such as a scooter, is movable from a first position, in which the marking device does not contact the riding surface, and a second position, in which the marking device contacts the riding surface. The marking device includes an attachment portion and a marking portion that creates markings on the riding surface as a result of frictional contact with the riding surface. The marking device can also include an actuation portion which is accessible to the user and allows the user to move the marking device to the second position. In one arrangement, the marking device includes an elastic marking member which is configured to bend in order to maintain contact with the riding surface.

Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The pantograph armature includes a motorized drive shaft with a drill tip for carving an outside surface of a crayon body, as well as a guide tip for tracing along a guide template that directs where the drill tip carves. In some embodiments, the guide template includes a stationary bridge support and a plurality of removable carving bucks that insert into one of multiple openings on the bridge support. The surface features of each of the carving bucks may be traced by the guide tip to generate a corresponding carving on the surface of a crayon body.

A storage assembly includes a first disk that may be positioned on a support surface. A storage array is provided and the storage array may contain a plurality of objects. The storage array has a plurality of bins and the objects may be positioned in the bins. The storage array is rotatably positioned on the first disk. A cover is removably coupled to the storage array. A handle is removably coupled to the storage array and the handle be manipulated thereby facilitating the storage array to be carried.

Writing compositions capable of undergoing a color development when brought into contact with a specific substrate including a color change-inducing compound are provided. Writing instruments comprising such writing compositions are also provided. Application of the writing compositions to surfaces other than the intended substrate will avoid color development and prevent staining of the unintended surfaces. The writing compositions include at least one mineral filler, at least one leuco dye, one or more lipids including one or more waxes, one or more fatty acids, or one or more fatty acid esters or fatty amides, titanium dioxide, and optionally at least one additive.
