The Karas Kustoms Fountain K is a compact, machined fountain pen that comes in aluminum, brass, and copper. This particular model features a black anodized aluminum body, and a silver aluminum grip. The thread-on cap uses triple-start threads to securely attach itself to the pen and to allow the removal of the cap with only 1.5 revolutions.

The clip and screws are made of durable stainless steel clip so you don't have to worry about breaking your clip like you do with most fountain pens. It comes with a standard international converter and a pack of short standard international cartridges.

Each pen is a little over 5" long and 1/2" in diameter (minus the clip). The aluminum version of this pen weighs 1.1 oz while the brass and copper versions weigh in at a hefty 3.3 oz.

The Fountain K uses German-made Bock steel nib assemblies known for their quality and long life. Interchangeable grip sections are available separately in other colors and materials and we highly recommend our Schmidt made Standard International converter for any additional converter purchases.

Karas Kustoms pens are designed and manufactured in the USA.
