TWSBI Diamond 580 Fountain Pen in Clear Demonstrator

The TWSBI (commonly pronounced “twiz-bee”) Diamond 580 is the 21st Century interpretation of a classic writing instrument. While most of our modern communication devices lack transparency and customization, the TWSBI Diamond 580 excels with a transparent resin construction that can be disassembled using the included wrench.The Diamond 580 represents the fusion of a traditional fountain pen with a modern industrial design. The result is an eye-catching writing instrument that is simultaneously appreciative of the past and relevant in the present. The modern writer can appreciate the stainless steel nib’s smooth writing quality, the high volume ink capacity, and the ability to take good care of their pen.The internal piston-filling mechanism holds about 2ml of ink and can be completely taken apart for thorough cleaning. Instructions and silicone grease are also included to aid in the maintenance of the pen.TWSBI Diamond 580 Clear Demonstrator Fountain Pen Specifications Edition: Standard Pen Material: Transparent Resin Nib Material: Stainless Steel Filling Mechanism: Internal Piston-Fill Mechanism (Bottled Ink Only) Pen Length, Closed: 5.59 in. / 142mm Pen Length, Open (Cap Off): 5.12 in. / 130mm Pen Length, Open (Cap Posted): Pen cap cannot be posted.
