TWSBI ECO Bahama Yellow Fountain Pen

Warm, understated and quietly distinctive, the TWSBI ECO Bahama Yellow offers a more refined take on colour. Rather than a bright or vibrant yellow, this shade leans into a deeper yellow brown tone, closer to soft caramel, giving the pen a richer and more mature character. The clear demonstrator barrel reveals the inner piston mechanism and ink level, creating a clean and technical foundation. The balance between transparency and colour feels deliberate and refined, with a subtle presence that still feels distinctive.

Designed for everyday reliability, the ECO features a smooth stainless steel nib that delivers consistent, controlled writing. The integrated piston-filling system provides a generous ink capacity, making it ideal for those who prefer bottled ink and longer writing sessions.

As with all ECO models, the Bahama Yellow can be fully disassembled for cleaning and maintenance (tools included), though TWSBI recommends this only for experienced users.
