Delta Bio+16 is the result of groundbreaking work with an advanced protein-based material. Originally limited to the colour ivory, this material has been transformed by Delta technical expertise, resulting in a spectrum of vibrant colours that expand the aesthetic potential of writing instruments.

The Bio+16 fountain pen features a distinctive design with 16 meticulously crafted concave facets, made with milling precision and mirror-polished. This unique design captures light in extraordinary ways, creating mesmerizing reflections.
Balanced ergonomics and aesthetics, one of the collection’s key innovations lies in its ergonomic design.

The concave facets are interrupted at a specific point on the body to make room for a smooth circular section. This transition from the faceted to the circular design is not just an aesthetic choice, but was designed to ensure maximum ergonomics during use. In this way, “Bio+16” offers the best of both worlds: a visually appealing structure and extraordinary comfort in the act of writing.
