Onoto - Ink Pencil - Fountain pen

1920ca Onoto "Ink Pencil" Stylograph Pen with red hard rubber, Eyedropper Filler, Stylographic Tip

Onoto Ink Pencil refers to a historic writing instrument introduced in the early decades of the twentieth century by the famous British house Thomas De La Rue & Company.

Although the name includes the word "pencil", it is not a graphite pencil like the one in the photo, but a stylograph pen (also known as a stylograph or stylographic pen).

The mechanical peculiarity and operation of this collector's item include:The barrel and the filling: Externally it resembles a classic fountain pen in ebonite or resin.

It used Onoto's iconic plunger filler system, which created a vacuum to draw liquid ink directly into the tank.

The tip (Stylus): Instead of the classic gold nib, the end has a small metal tube with a thin gold or platinum wire inside mounted on a tiny spring.

As he wrote: When the tip touched the paper, the pressure made the thread retreat, opening the valve and letting the ink flow evenly, simulating the precise and constant stroke of a pencil but with the permanence of the ink.

the Onoto Ink Pencil is to all intents and purposes a liquid ink pen designed for those looking for a fine, constant graphic stroke without line variations.
