The fusion one collection of writing instruments combines the best of delta's engineering capabilities with traditional italian craftsmanship. Fountain pens and capped rollerballs are turned from a special resin, worked by hand from solid bars, and polished to a mirror-like surface in three bold colors; black, red, and white. The distinctive clip is forged from a special metal alloy designed for strength and flexibility, then coated with platinum.

Fusion one is fitted with delta’s new and innovative 18kt gold fusion nib- a revolutionary nib whose performance and beauty belie its moderate cost. Free-flowing and smooth, the 18k fusion nib. The fountain pen accepts a standard cartridge and a converter while the smooth writing roller fills with standard refills.
