About the TWSBI VAC700R Vacuum Filler Fountain Pen – Kyanite Blue

The TWSBI VAC700R Vacuum Filler Fountain Pen – Kyanite Blue is an engineering marvel designed for writers who demand endurance and reliability. Unlike standard cartridge pens, this model utilizes a sophisticated vacuum filling mechanism that uses negative pressure to fill the entire barrel with ink in a single, satisfying stroke.

What sets this Special Edition apart is the stunning two-tone nib. The large No. 6 stainless steel nib (crafted by Jowo Germany) features specialized blue plating that perfectly matches the pen's Kyanite blue trim—a subtle but striking detail found only on this model.

With a massive ink capacity of approximately 2.4ml, the VAC700R is built for marathon writing sessions without the need to refill. It also features a unique ink shut-off valve; when the knob is fully tightened, it seals the ink reservoir from the feed. This makes the VAC700R one of the few fountain pens truly safe for air travel, as it prevents pressure changes from causing leaks.

True to TWSBI’s philosophy of user empowerment, the pen arrives in a presentation box that includes a wrench and silicone grease, allowing you to fully disassemble and lubricate the mechanism yourself—ensuring your pen lasts a lifetime.
