The lead is surrounded by a casing, usually coloured to match the filling colour, which is fitted with a cap to protect it from drying out.At the end, a differently shaped writing, drawing or painting tip transports the writing fluid from the core to the surface to be written on or painted. In the past, this tip was usually made of felt. Today, tips made of plastic with defined capillaries are mostly used. Felt-tip pens are in principle refillable.
Felt-tip pens containing solvents are particularly affected by the problem of drying out during transport to the consumer. As a solution, felt-tip pens with unimpregnated tips were first developed. Before such pens were used for the first time, the consumer had to push hard on the stable tip to penetrate an internal membrane to allow the ink to impregnate the tip.
The German chemist Adolf von Baeyer developed indigo synthesis and synthesised fluorescein in 1871. Adolf von Baeyer developed fluorescent pens for his children, which were then used in offices to mark passages of text.
The US American Sidney Rosenthal invented the felt-tip pen in 1952, which he then called the "magic marker". The first fibre-tip pen was the "SignPen" model by Pentel (Japan) in 1962, invented by the Japanese Yukio Horie.
