Each pen includes a wrench and silicone grease for servicing the piston system when needed, though these tools are not required immediately. TWSBI encourages thoughtful and careful handling when exploring the pen’s internal components, particularly the feed, which is delicate and should only be removed when absolutely necessary. With its blend of affordability, durability, and thoughtfully designed features, the TWSBI ECO Fountain Pen in Plum with Onyx Trim offers a writing experience that feels far beyond its price point. Its bold look, reliable performance, and transparent design make it an appealing choice for anyone wanting a quality piston-filled fountain pen.
