A writing, drawing, marking and/or cosmetic device, wherein the device includes at least one shaft and at least one inner body, wherein the at least one shaft is formed from concrete-containing material. The shaft at least partially surrounds the inner body. In the installation position the shaft is secured in an axial direction against axial displacement by a closing cover and a front part and a prestress is formed in the shaft in the axial direction via the closing cover and the front part.

A novel blending stump pencil device that provides a user with one implement for both drawing and blending is disclosed. The device comprises a wood-bodied pencil with a blending stump attached to a rear of the pencil via a securing apparatus. The device comprises a clear finish and a removable plastic sleeve that protects the blending stump from damage and debris. Further, the device can be included in a kit with multiple pencil types.

A body for a writing, tracing, drawing or coloring pencil has a composition that has, by weight, with respect to a total weight of the body between 50% and 95% of a mixture of polylactic acid and polybutylene succinate in a polylactic acid/polybutylene succinate ratio by weight of between 90/10 and 60/40 and between 5% and 50% of filler that includes an organic filler, such as wood fibers. A writing, tracing, drawing or coloring pencil includes such a body.

An extension for pencils with wearing leads, formed from a thin-walled hollow profile. The inner cross section is adapted to the shape of a pencil. One or more slots of appropriate length in the longitudinal direction at an end of the extension where the tapered end of the pencil is located and a slight linear reduction in the cross section approximately over the length of one or more slots. Longitudinal raised sections in the form of triangular, square, and/or semi-circular prisms, directed inwardly. The height of the raised sections may increase in the direction of insertion of the pencil and dig into the pencil slightly when the pencil is inserted. The height of the raised sections is reduced linearly to zero at the end of the extension where the pencil is inserted. Inwardly bent or protruding retaining springs arranged on the inner surface of the extension.

In a pencil lead manufactured through a baking step regardless of being a black lead or a colored lead, the mechanical strength of the pencil lead is further increased by coating a surface thereof with a resin. A pencil lead includes a baked lead body whose surface is covered by a covering layer made of resin that has a scratch hardness of HB or greater. The scratch hardness of the resin as a subject resin is defined as a lowest hardness index of a tester pencil that is able to form an indentation on a surface of a horizontal flat plate coated with a 5-μm thick film of the subject resin, when the surface is scratched by the tester pencil being pressed onto the surface at an angle of 45° with a load of 7.355 N.

An apparatus for securing a writing implement to a complementary magnetic surface. The apparatus includes a body formed of a ferromagnetic material, the body extending between a first end and a second end of the housing. A first and second end of the body defines an opening that forms a channel extending between a plurality of lateral interior surfaces from the first end to the second end. In an embodiment, a protrusion is disposed within the housing and extends from one lateral interior surface toward the channel. In an embodiment, a stopper may be disposed proximate to the second end of the body and partially extend from a lateral interior surface toward the opening. In an embodiment, the housing receives the writing implement, and a protrusion contacts the writing implement securing it in place.
