A non-marking, writing system simulates a physical writing system which has characteristic ranges of writing resistance, sound, resilience and thermal conductivity. The non-marking writing system includes a non-marking writing instrument having an elongated shank with opposite ends. A non-marking tip is connected to one end of the shank for engagement against and movement across a writing surface. The writing surface onto and across which the tip is moved for non-marking writing, creates an actual writing resistance. The tip is structured and made of selected material and the writing surface is made of selected material so that the actual writing resistance falls within the characteristic range of writing resistance for the physical writing system.

A non-marking, writing system which simulates a selected physical writing system having characteristic ranges of writing resistance, sound, resilience and thermal conductivity, the non-marking writing system comprising: a non-marking writing instrument having an elongated shank with opposite ends; a non-marking tip connected to one end of the shank for engagement against and movement across a writing surface; a writing surface onto and across which the tip is moved for non-marking writing under an actual writing resistance; and the tip being structured and made of selected material and the writing surface being made of selected material so that the actual writing resistance falls within the characteristic range of writing resistance for the selected physical writing system; movement of the tip onto and across the writing surface producing sound, the system including selecting the structure and material of the tip and writing surface so that the sound falls within the characteristic range of sound of the selected physical writing system.
