Natural Ultem, Black Ultem and Peek
The first full sized fountain pen from Schon DSGN! I say full sized since it fits not just cartridges that fit in this pen but a converter as well. I personally love small pens so this was a design exercise out of my comfort zone. This pen uses a Schmidt K5 converter and houses a Jowo #6 nib. It was also designed to be a compact pen as that is my style. Gold nibs can be purchased here for this pen and can come as a spare or installed into the pen.
It is jam packed with O-rings in the section to create a strong pen for eyedropper use ( no converter, filling the full body with ink). Here's a video about how to eyedropper a pen, why/why not, some nerdy stuff etc. Be sure to have some silicon grease handy as it makes the process much smoother and keeps the seals happy!
The material is Ultem aka PEI (Polyetherimide) and is able to be machined thinner than most acrylic pens and yet will be stronger than acrylic to resist accidental drops or mishaps.
The o-rings will keep the pen sealed so excessive tightening of the section to body and cap to body is not necessary.
Uncapped length - 122.5mm(4.80”)
Grip diameter min- 10.2mm (.40”)
Grip diameter max - 11.2mm (.44”)
Body diameter is 13.5mm (.530”)
Weight- 1/2 oz or ~ 14grams (Ultem and Black Ultem) 15 grams (Peek)
The cap does "post" and it is very comfortable to do so due to the extremely light weight cap.
What chemicals can I use to clean this pen? Soap and water or Alcohol is fine on this material for deep cleaning (one of the benefits of Ultem and Peek!)
What chemicals should I not use? Windex. Ammonia based chemistry, It has been brought to my attention that some pen flush has ammonia, use that only on the nib/feed. It is easy to unscrew the nib unit and do that, if you need help ill make you a video to show you how.
