It is a limited edition of only 399 unique pieces, made of rare celluloid with a very original design.

It brings with it an innovation represented by an unprecedented weight balancing system, just patented under the name “Write Balance”, designed to offer the user a personalized comfort.

At the barrel end of the “39+1” fountain pen is a threaded cone, and within that cone is a two-gram gold plated removable weight.

With the weight inserted into the cone, the fountain pen’s balance is toward the back end, meaning that the user’s hand is more involved in the writing.

This center of gravity is often preferred by calligraphers and lettering artists for greater control of the fountain pen’s movement.

With the weight removed from the “39+1”, the balance shifts toward the front of the pen, meaning that the pen is doing the work, not your hand-great for long writing sessions and more casual writing.

The Weight “Write Balance System” offers the possibility of being able to choose the best personal balance according to one’s grip and writing characteristics.

The different sensations could appear minimal, but it becomes significant in terms of feeling, pleasantness and comfort of use, especially during long writing sessions.

Delta fountain pens are known for their responsive writing experience, and the “39+1” is no exception.

The cartridge/converter/eyedropper-filling fountain pen has an 18-karat gold Delta nib engraved with the Delta signature logo, available in Extra Fine, Fine, Medium, Broad and Stub 1.1 widths.

Aesthetically, the new Delta “39+1” is an extraordinary combination of technical consideration and artistic sensibility.

The mottled brown and black celluloid is hand turned and highly polished, matched to gold-plated appointments.

The barrel features a deeply curved grip section leading into gold-plated threading.
