Tango Silver Rollerball Aquamarine. This beautiful Tango silver & Aquamarine rollerball is a new design from Waldmann. The Rollerball has a sterling silver cap and lower barrel, which has been lacquered with brilliant Aquamarine lacquer. After lacquering, the imagination pattern has then been engraved through the lacquer to show off the sterling silver. The component parts such as the clip have been plated in platinum and the rollerball is also fully hallmarked. The Tango Silver Rollerball has a screw-off cap and will be in a luxury presentation box including a 10-year guarantee and a silver cleaning cloth. All our silver pens are made by skilled craftsmen and women at Waldmann in Germany. Also available as a Ballpoint and Fountain Pen. See below for matching pens, refills, and accessories.
