TWSBI Diamond Mini V2 Fountain Pen, White + Rosegold

Variant
Regular price $84.99
TWSBI fountain pens are notorious for their high-quality and special filling systems normally found only on much more expensive pens. The Diamond Mini features a high-capacity filling mechanism similar to TWSBI's full-sized fountain pens, and puts it into a compact pen that is perfect for everyday carry. Simply uncap and twist the end cap to extend the piston, dip it into ink, and screw back the end cap to fill. Just like that - you're ready to write and there is no need for cartridges or a converter! Thanks to the clear barrel, you can always see your ink level. The faceted transparent barrel highlights your ink, and shows of the inner workings of the pen. 

In keeping with their philosophy of promoting the traditional experience of using a fountain pen, TWSBI has designed this pen to be completely self-serviceable. It comes with a wrench and a vial of silicone grease you can use for at-home maintenance. Don't worry... this is only for long-term care and nothing you have to think about right away.

TWSBI (pronounced TWIZ-BEE) has become a staple in the fountain pen community, known for its high-quality, piston and vacuum-filling demonstrator pens at an exceptional value. Though it may seem like a newer brand, TWSBI’s history spans over 50 years as Ta Shin Precision, an OEM manufacturer producing parts for well-known brands. A decade ago, the company shifted to designing its own pens, combining traditional craftsmanship with modern innovation.

With a name inspired by Chinese calligraphy, TWSBI is dedicated to creating durable, high-performing pens featuring smooth stainless steel nibs, excellent cap seals, and transparent designs that showcase their intricate filling mechanisms. Their user-serviceable approach, with included tools for maintenance, makes them a favorite among writers, professionals, and pen enthusiasts looking for reliability, style, and a hands-on writing experience.
