This is a Blue/White Corian slimline Twist Pen. Corian is the counter top material that is used in kitchens. Pen is made with Black Chrome accents. The pen uses a Cross® style refill that features a premium Swiss-made carbide writing tip for smooth consistent writing. To replace the refill, pull off top of pen above the center band and twist out the refill. A highly polished lacquer finish was used to protect the Corian. These hand made pens and pencils make wonderful gifts and are absolute treasures to own!
