Back to the Future is a limited edition of 949 fountain pens or roller pens with a single world numbering system.
The shape is inspired by the quill, the writing implement of the ancient Egyptians and Romans, made from a cane or rush and used right up until the 6th century AD before being gradually replaced by the goose-feather quill.
The cap and barrel are in carboiridium, a carbographite cane with a special finish in spiralled carboiridium lending it a moiré effect whenever it is exposed to direct light.
The clip, a further variant of the goose-feather quill, has a technical sophistication for its design motif and the mechanism is miniaturised and concealed in its interior.
The fountain pen has an extra-flexible nib in 14 carat gold and a piston filling system.
