A sanitary sleeve comprising a body configured to be grasped by a hand of a user, the body extending from a first end toward a second end along an axis, the body including a plurality of layers configured to be removed one at a time, and the plurality of layers including at least a first layer and a second layer, and wherein removal of the first layer of the plurality of layers exposes the second layer of the plurality of layers.

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.

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 filler; at least one leuco dye; at least one lipid including at least one wax, at least one fatty acid, at least one fatty acid ester; an antioxidant; and optionally at least one additive.

A tool for marking livestock is a cylinder of marking material enveloped by a sheathing. The sheathing is segmented annularly at intervals along the vertical axis and each segment and is cut vertically so that it can be removed in sections to gradually reveal more of the marker.

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 kit may further include a wrapper removal mechanism configured to remove a wrapper from a crayon, such that the crayon carving device may be used on an exposed crayon surface.

A crayon wrapping system for exposing a crayon that becomes shorter from usage includes a crayon that may be manipulated for coloring. A wrapper is wrapped around the crayon such that the wrapper forms a helical coil on the crayon. Moreover, the wrapper is selectively peeled away from the crayon as the crayon becomes shorter from usage.

A seed-containing crayon. The crayon includes an elongated member formed of a marking composition to leave a colored mark on a surface when the elongated member contacts the surface. The marking composition is formed of a wax, a pigment, and a plant nutrient that is activated by application of water to the elongated member. Plant seeds are embedded in the marking composition of the elongated member. The crayon can include a paper band that at least partially surrounds the elongated member along at least part of the length of the elongated member in which the plant seeds are embedded.
