Engineered Plastics "Full Sized" Fountain Pen - Ultem/Peek/Black Ultem
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 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 (or some other options below!). Even though it fits a converter, it was also designed to be a compact pen fitting with my style.
Grips
I made a #8 (Bock 380) grip section for this pen in Black and Natural Ultem and that can be purchased here if you want to provide your own Bock 380 nib for the pen.
I also made a Rollerball Section which can be purchased with the pen or solo here.
Mix and Match #6 sections in black and amber can be purchased here.
What is Ultem?
The material Ultem aka PEI (Polyetherimide) is able to be machined thinner than most acrylic pens and yet will be stronger than acrylic to resist accidental drops or 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 also made this design in Peek.
O-rings
The o-rings will keep the pen sealed so excessive tightening of the section to body and cap to body is not necessary.
Specs
Capped length-127.5mm(5.02”)
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)
Posting
The cap does "post" (with the exception of the straight wall models) and it is very comfortable to do so due to the extremely light weight cap.
Cleaning
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.
