In the rapidly changing world around us today, speed is becoming more important in business. With the new Platinum Curidas retractable fountain pen, there is a great writing tool available to use immediately without the need of removing a cap. The nib retracts and when closed, a high sealed nib pocket made of soft material enhances airtightness. The well-designed clip is not obstructive to the hand, and can also be removed.

In 1919, Shunichi Nakata, started his fountain pen business that would later be known as “Platinum Fountain Pen Co.”. The Japanese brand is closely related to the legendary Nakaya fountain pen brand, where some of the finest fountain pens in the world are created. This expertise also goes into Platinum's own line of fine writing instruments.
