Inspired by the deep, ripe tones of late summer fruit, the TWSBI ECO Plum with Onyx is a bold yet elegant addition to the TWSBI lineup. This edition pairs a rich plum-coloured cap with sleek onyx-black accents, creating a refined contrast that stands out on any desk. The transparent demonstrator barrel showcases the internal piston-filling mechanism and ink supply, celebrating the precision and functionality that define the ECO range. The cap’s glossy plum finish is complemented by polished black hardware and the signature TWSBI red logo on the finial. A stainless steel nib ensures a smooth and consistent writing experience, while the high-capacity piston-fill system allows for extended writing without frequent refills. The screw-on cap includes a rubber O-ring for a secure, leak-proof seal.

As with all ECO models, this pen can be fully disassembled for thorough cleaning and maintenance (tools included), though disassembly is recommended for experienced users only.
