Here is a very nice professional style pen. The oversized tip gives the pen a nice feel and makes it comfortable to write. The two-tone finish on the tip and back strips gives the pen a layered and exquisite look. It is made with a silver-blue DiamondCast blank with diamond brilliants that is made from premium urethane, real diamonds and the best liquid and powder pigments available on the market. Each batch is poured into molds by hand, which creates unique patterns and spirals in each blank. This pen uses a "parker" style cartridge found in stationery stores.
