"Rings Black/White" Roller Ball Pen is designed by Robert & Trix Haussmann, and is made from acrylic colors mixed together. The result is a pen with a set shape, but whose colors are completely unique from pen to pen, so every pen is one of a kind. This "Rings" pen comes with a pen display with a base that use created in the same way. This pen display was previously only used in stores and tradeshows and is available here while supplies last.
