TWSBI ECO Fluorite Purple with Bronze Fountain Pen.

Experience the vibrant, mystical charm of the TWSBI ECO Fluorite Purple with Bronze. This captivating addition to the celebrated ECO collection features a swirling, multi-tonal purple and pink cap and piston knob, reminiscent of rare fluorite crystals. The design is beautifully elevated by sophisticated bronze-toned trim and a matching bronze-colored stainless steel nib, creating a warm and luxurious contrast.

The signature crystal-clear demonstrator barrel provides a front-row seat to your ink's movement, turning your favorite fountain pen ink into a central part of the pen's aesthetic. Renowned for its reliable performance and massive ink capacity, the ECO (Economical) remains the ultimate choice for those seeking high-end piston-filler engineering at an accessible price point.

Key Features:

• Integrated Piston Filling System: A high-capacity internal reservoir that draws ink directly from the bottle with a simple twist—no cartridges or converters required.

• Transparent Demonstrator Body: The high-quality acrylic barrel reveals the intricate internal piston mechanism and your current ink level at a glance.

• Bronze Trim & Nib: Features a unique bronze-finished clip, cap band, and polished stainless steel nib for a refined, vintage-inspired aesthetic.

• Airtight Cap Seal: An internal O-ring seal prevents ink evaporation and ensures the nib stays wet and ready to write immediately.

• Maintenance Kit Included: Every TWSBI ECO comes with a wrench and silicone grease, allowing you to perform your own long-term servicing and cleaning.
