Leather twist ballpoint pens exhibit a unique vintage shiny nickel finish over solid brass metal core. These pens offer wondrous features like a twist-action mechanism that brings the pen refill into the writing position, a European black ballpoint ink cartridge, and a vinyl wrap on the bottom barrel. They also have a metal pocket clip attachment on the top which makes it easy to clip them to your pockets. These pens are comfortable to hold and render clear and smooth handwriting.
