From the collaboration between Marlen and Fountainpen.it comes Aleph, a flat top fountain pen with piston filling and a nib with a flexible, harmonic steel. The Aleph pen is made of gray resin with mother-of-pearl shades, or in solid black, and rhodium-plated trim finishes. Clean lines and simple but elegant decorations, make Aleph an instant classic pen ideal for everyday use. The great novelty is the flex nib, made of harmonic steel, which ensures a good memory effect for moderate bends (1.00 to 1.50 mm). The sinuous shape is characterized by the two lateral cuts, which not only have an aesthetic but also a functional task, as they serve to limit the force necessary for the bending of the nib. The ventilation hole is in the shape of a heart. Adding to the functional benefits of the nib, is the beauty of the transparent feeder which allows non-black inks to be brilliantly seen.
