Schon DSGN Engineered Plastics “Full Sized” Ultem Fountain Pen
This pen is lovingly used and does not come with a box or papers. It is equipped with a Steel Gravitas Fine nib and fills via Cartridge/Converter (included).
From Schon DSGN:
The first full sized fountain pen from Schon DSGN! I say full sized since it fits not just cartridges but a converter as well. I personally love small pens so this was a design exercise out of my comfort zone. Even though it fits a converter, it was also designed to be a compact pen fitting with my style.
What is Ultem?
The material Ultem, aka PEI (Polyetherimide), is able to be machined thinner than most acrylic and yet will be stronger than acrylic to resist damage from accidental drops or other mishaps. I love Ultem as I started my career before pens making scientific instruments out of this material. Plus it has the cool yellow/amber color in its natural form. Peek is another very cool engineered plastic, so I made this design in Peek as well.
O-Rings
This pen has an o-ring in the cap for a smooth closing action and leak proof seal. It’s jam packed with o-rings in the section to create a robust platform for eyedropper use, filling the pen body with ink rather than using a cartridge. Be sure to have some silicon grease handy as it makes the process much smoother and keeps the seals happy!
The o-rings will keep the pen sealed, so excessive tightening of the section to body and cap to body is discouraged as it may damage or deform parts.
