Made from protein-based certified organic material, these eco-friendly pens feature 16 polished facets, offering an ergonomic and elegant design that prioritizes both comfort and aesthetics. Completely free of plastic, each pen is a perfect fusion of tradition and innovation.

Each Delta Bio+16 fountain pen is hand-turned from solid bar stock using 100% organic protein-based material. The concave milling of the body creates 16 polished facets, paired with 24-carat gold-plated metal components. The signature “Charm” clip is hand-engraved, milled from solid bar stock, and meticulously finished.

The pen features a fixed piston filling system, crafted in the Maiora workshops, and is fitted with a 14kt gold #6 nib for a premium writing experience.*

Individually numbered, each “Bio+16” pen is unique. Though not a limited edition, the intricate production process, requiring six months per batch, ensures exceptional exclusivity.
