This set includes a converter, one cartridge, and a 20 ml bottle of blue fountain pen ink. The Platinum Curidas is designed for effortless writing with a single click, catering to the need for speed in our fast-paced world. With the Curidas, you can write instantly without the hassle of uncapping, ensuring you never miss an opportunity to jot down important notes. The term "Curidas" is a blend of "Curidasu," a Japanese term signifying the extension of the pen tip, and "Curiosity." This innovative fountain pen was created to satisfy people\'s curiosity. From a technical standpoint, the Platinum Curidas introduces several notable advancements compared to other retractable fountain pens. The unique nib pocket utilizes two plastics of varying hardness to maintain optimal nib moisture, and its size is minimized for this purpose. Equipped with a slim, elongated stainless steel nib, the Platinum Curidas provides enhanced control over the pen tip while writing. The well-designed clip, unobtrusive to your hand, can be easily removed using a special key included in the box.
