Delta, an established Italian pen manufacturer, re-entered the market after ceasing operations in the 2010s. Their new model "Duna" is handmade in Naples, Italy, featuring a simple yet elegant design with a vintage-modern style. It includes a classical ball clip, conical tip, piston-filling mechanism, and an ink window for monitoring ink levels. The pen has a matte black finish and its trim color matches the rose gold nib crafted from high-quality stainless steel by JoWo, a German brand. The fountain pen version offers a flex nib, allowing users to vary line thickness with pressure. The Duna is also available in ballpoint version.
