The present invention thus relates to a writing or color pencil comprising the following 3 layers obtained by coextrusion a polyolefin-based non-expanded lead, a non-expanded protective intermediate layer surrounding the lead and comprising a mixture of polystyrene and EVA, and an expanded synthetic wood material based on a styrene polymer surrounding the protective intermediate layer, the protective intermediate layer thickness/lead radius ratio being between 0.05 and 0.17, advantageously between 0.07 and 0.15.

The present invention concerns an extrudable, unexpanded paper pencil lead, comprising, by weight relative to the total weight of the lead, between 40 and 60%, and advantageously between 44 and 50%, of graphite; between 15 and 40%, and advantageously between 20 and 35%, of a polyolefin; between 5 and 15%, and advantageously between 6 and 10%, of a colorless mineral filler; between 5 and 20%, and advantageously between 5 and 15%, of carbon black coated with or mixed with a polyolefin wax or a polyolefin; between 0 and 16%, and advantageously between 5 and 15%, of an additive. It further concerns the paper pencil comprising a lead according to the invention.

A writing instrument that comprises a writing instrument base and a focus tool is provided. The writing instrument base includes a marking system coupled with a barrel. The marking system is configured to provide writings on a writing medium, such as paper. The focus tool is coupled with the writing instrument base. The focus tool is configured to blend in with the writing base. The focus tool includes a device that engages a user's senses and reduces the negative impact of attention deficit disorders when used by the user. The fidget tool stimulates the user's vestibular system and proprioceptive senses through one or more of the following: movement, sound, smell, visual, and tactile action. The fidget tool may be discreet such that the tool is hidden or not viewable when not in use.

A colored lead for writing, drawing and coloring implements, more particularly erasable, sintered colored lead, or to a colored chalk, more particularly erasable, sintered colored chalk, having a sintered lead or chalk base body which is formed from a lead or chalk base material containing at least one binder with a proportion of from 1 to 25% by weight and at least one filler with a proportion of from 25 to 99% by weight. The sintered lead or chalk base body is impregnated with at least one colorant and at least one lubricant.

An art medium applicator includes a rotating shaft and an art medium coupled thereto for causing the medium to travel through an application path for transfer to a substrate. The applicator includes a coupling assembly, and may include an applicator tip including a cavity into which the art medium is inserted and supported. An art medium modifier includes a rotating shaft and an art medium modifier coupled thereto for causing the modifier to travel through an application path for modification of an art medium previously applied to a substrate.
