The Cabernet ‘Garnet’ is a mesmerizing rollerball pen featuring a barrel in Birds Eye rhyolite, and a light structure in aerospace grade titanium and aluminum. The accents on the carbon fiber cap are in mokume and sterling silver; the pocket clip is set with a white topaz gemstone. This beautiful writing instrument also features William Henry’s patent-pending Wavelock� cap closure system � a ring of chromium steel balls embedded in a titanium ring which are captured in wave-shaped grooves in titanium collars for closed and post positions.
