Embodiments of the invention are directed to a roller ball marking instrument for use with paint, a method for assembling the roller ball marking instrument, and a system for delivering paint. The body of the marking instrument includes a reservoir for storing paint. The body is coupled to a fibrous roller ball via a retaining ring. The roller balls sits within a partially-enclosed cavity in the center of the retaining ring. A least part of the roller ball protrudes through an opening in the retaining ring. Paint in the reservoir moves first through an opening at one end of the body and then through an open center of the retaining ring. The paint is transferred to the roller ball. The roller ball rotates freely within the cavity of the retaining ring and transfers the paint to a writing surface.

A device for marking a surface, the device comprising: a body configured to store a marking substance; a guide arrangement having a first end and a second end, at least a portion of an outer surface of the guide arrangement tapering from the first end to the second end which is narrower than the first end, wherein an output path is provided through the second end at substantially the center of the guide arrangement; an activation arrangement; and a delivery arrangement which is configured, in response to triggering of the activation arrangement, to deliver a quantity of the marking substance from the body, along the output path and out of the second end, wherein, in use, a user inserts at least the second end of the guide arrangement into an aperture in an element positioned adjacent a surface until the outer surface of the guide arrangement contacts the aperture, and the user triggers the activation arrangement to deliver a quantity of the marking substance through the second end and onto the surface to mark the surface at a position which is substantially aligned with the center of the aperture.

The present invention relates to a multifunctional clay composition which can be used as a clay capable of performing various workings before drying and which can be used as writing instruments similar to crayons, pastels or colored pencils after drying, and to a process for preparing the same. The multifunctional clay composition may comprise an extender material; a binder; a multifunctional crosslinking agent including a compound having a hydroxyl group of two or more functionality, or forming an ion having a hydroxyl group of two or more functionality in a water solvent; a wax and a pigment.

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 magnetized writing and amusement device. The device having a first end and a second end. Each of the ends having a magnet embedded with the interior. The magnetics allowing for the coupling of multiple devices together. The first end functions as a cap for the device and conceals a writing implement located within the internal structure of the device.

The invention relates to a biodegradable and/or compostable core or crayon for writing, drawing, and/or cosmetic purposes containing at least one fatty acid ester, at least one metal soap and/or soap, and at least one colorant, wherein the at least one fatty acid ester and the at least one metal soap and/or soap are included in a total proportion of 33 to 90 wt. %.

The invention furthermore relates to a pencil comprising such a core and to a method for producing such a core or crayon.
