WHAT IS ULTEM?
Ultem is an engineered plastic also known as Polyetherimide (PEI). It is an amorphous plastic that offers high strength, excellent chemical resistance with a high service temperature. It has a distinct amber-to-transparent color. It is commonly used in autoclave applications, high voltage circuit breaker components, and jet engine components. In the fountain pen world, it is used because of its attractive amber color and excellent mechanical properties. It is stronger than acrylic and other resins and excellent for precision machining.
Our PIUMA pocket fountain pen is very compact, but when posted it is the same size as a regular pen. In addition, it features a large #6 nib and a wide grip section, which provides a very comfortable writing experience.
INK CARTRIDGES, EYE-DROPPING
The pen accepts all standard international ink cartridges which are widely available worldwide. All pens will include one black ink cartridge. In addition, you can also use a bulb aerometric converter (not included). We also understand the passion for diverse ink options for fountain pen enthusiasts. For this reason, these pens have been designed for eye-dropping capabilities. The body threads have been calibrated to stop the ink from going through. In addition, we incorporated an o-ring seal that prevents any leakage. Silicone grease is recommended to be applied on the nib unit threads and on the barrel threads.
The pen comes equipped with a large #6 nib made in Germany by Peter Bock. These nibs have been regarded as one of the best performing nibs in the business. All pens come with a choice of black lacquered stainless steel nib or a polished stainless steel nib.
Our PIUMA pocket fountain pen has received praise from fountain pen experts. You can watch their reviews on YouTube.
