Beautifully crafted black ink pen. both ends of the pen are metal and feature delicate designs recognizable in connection to Clamp's xxxHOLIC series.  The copyright is also etched into the end of the metal pipe.   The middle is the brown colored plastic tube of the pen. 

Because the metal ends are of solid metal (except for the pipe part which is the cap) the pen is quite heavy and is mostly kept as a collector's item.
