Machined to perfection using a mixture of metal and walnut wood, the Ritma Walnut boasts a streamlined design from magnetic cap top to back post, perfect for those who prefer a well-balanced and heavyweight rollerball pen. Polished gunmetal accents. Clip designed to match the straight lines of the body style with a center cut in an elongated oval shape. Magnetic cap and posting: So secure and perfectly designed to the rollerball pen, it creates a seal. No need to twist off, gently pull and enjoy the striking pop-action sound of the seal opening, then post to the back to experience the secure magnetic seal there as well. The capped rollerball pen adds a touch of elegance and practicality with its smooth writing refill.
