Delta Butterfly Fountain Pen - Yellow Swallowtail (Special Edition)
The new Butterfly fountain pen collection from Delta is a tribute to the beauty and variety of colors in nature. Each pen is inspired by the grace and lightness of butterflies, a symbol of transformation and freedom. A sensory journey through the art of writing, where each word comes to life like the flutter of a feather in the wind.
The Yellow Swallowtail features a vibrant flecked yellow resin barrel. It is complemented by a solid black cap, grip section, and bottom finial. The cap's centerband features a ring of blue. It also has a beautiful butterfly design on both the nib and on the top finial.
This fountain pen uses a threaded standard international converter, has gold-plated trim, and a gold-plated #6 JoWo steel nib. Each pen is handmade in Naples, Italy and comes with a bottle of yellow ink.
This special edition color is only available at Goulet Pens, not individually numbered.
