Here is a very nice Liberty twist ballpoint pen made of stainless steel. The components of the pen are machined from stainless steel in the USA. 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.
