Artists from the late Medieval period through the Renaissance used a small, sharpened metal rod for drawing precise compositions on paper or parchment. While the metal could be lead, silver, copper or gold, silver was used most often due to its suitability for permanent drawing. Using the same technique (without the silver part though), Grand Illusions has come up with an "inkless" pen that can write on virtually any type of paper.

The pen looks like any other normal stainless steel pen but the difference is visible when you unscrew its top. The solid metal 'nib' is made of a metal alloy and is capable of leaving its mark on most types of paper. On normal paper, the pen leaves writing similar to that of a pencil. However, there' no chancesof the writing getting smudged or being rubbed out. Theoretically, the pen can last infinitely since there is no ink to dry out, but I would expect the nib to wear off after a few years of grinding against paper.

Currently out of stock, this pen is available for $29.38.
